            Bug ID: 110214
           Summary: amdgpu: xterm scrollback buffer disappears while
                    paging up/down
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: diego.viola@gmail.com

Whenever I run `dmesg' on a xterm that uses the following options:

xterm -fa "DejaVu Sans Mono:style=Book:antialias=true" -fs 9

and I scroll up with the keyboard (shift+page up) parts of the scrollback
buffer disappears, making it difficult to read the output.

I've tested other terminals (urxvt and alacritty) and I cannot trigger the bug
with these terminals, with xterm it happens only with xft and with the options
I mentioned above.

Steps to reproduce:

- run `xterm -fa "DejaVu Sans Mono:style=Book:antialias=true" -fs 9'
- run `dmesg', hit enter and page up

You should notice parts of the buffer disappearing.

I use the modesetting DDX driver, I also tried the xf86-video-amdgpu DDX driver
and I can reproduce it with both, however, when setting Option "Accel" "off" in
/etc/X11/xorg.conf.d/20-amdgpu.conf I cannot reproduce it anymore.

Actual Results:

As mentioned, the scrollback buffer disappears when paging up with these xterm
options that I mentioned above.

Expected Results:

xterm works normally with these options, with no scrollback buffer issues.

System details:

- Arch Linux (x86_64)
- linux 5.0.2-arch1-1-ARCH
- xorg-server 1.20.4-1
- i3-wm 4.16.1-1
- xterm 344-1
- mesa 19.0.0-1

My machine is a "AMD Ryzen 5 2400G with Radeon Vega Graphics" APU with
integrated vega graphics.

Please attach the corresponding Xorg log file and output of glxinfo and dmesg.

I can't seem to reproduce this, and I'm not sure what exactly "parts of the
scrollback buffer disappear" means. Maybe you can make a screencast or
screenshots demonstrating the problem?

Anyway, this is more likely an issue between glamor and Mesa than in the kernel
driver. Reassigning to Mesa for now, as glamor issues are no longer tracked
here.

By that I mean the actual text/output disappears after I do shift+page up, but
it doesn't if I scroll with the mouse wheel or if I use the scrollbar.

I've attached a video demonstrating the issue, please let me know if you need
more info.

Thanks.

That was wrong, using the scrollbar also causes the same effect as using
shift+page up (disappearing text).

I've compiled mesa from git and the issue is still there, I also tried older
releases like 18.3, 18.2 and the issue remains.

I also tried recompiling xorg-server (git and 1.20.0) and the problem still
persists with those, I can't compile older releases anymore due to compile time

How exactly did you set that? Normally, I'd expect it to only affect clients,
not the X server.

Are you using a compositing manager?

In my TT1:

export LIBGL_ALWAYS_SOFTWARE=1

then startx after that.

When I'm on X, I open an xterm and LIBGL_ALWAYS_SOFTWARE=1 will be set, glxinfo
also reports llvmpipe.

I'm using i3-wm, no I don't use a compositing manager.

Did you build xserver with meson or autotools?

BTW, I'm not sure if it's related, but I also started seeing some artifacts
with GTK windows (GIMP and LibreOffice), items such as "Help" (in GtkMenuItem)
will disappear, then they re-appear until I click in one of them.

The same is also true for the text in the menus itself.

[Bug 110214] amdgpu: xterm scrollback buffer disappears while paging up/down

[bugzilla-daemon]

[-- Attachment #1.1: Type: text/plain, Size: 686 bytes --]

https://bugs.freedesktop.org/show_bug.cgi?id=110214

--- Comment #24 from Diego Viola <diego.viola@gmail.com> ---
I've bisected the issue with the GTK elements sometimes disappearing, and the
commit that causes the issue is this one:

1b25d340b791ad8350bdfb27f1a91ac79fa17748 is the first bad commit

Sadly my xterm is still affected but I can confirm this commit causes the issue
with the GTK windows, going back to the previous commit fixes the issue with
the invisible element in GIMP.

Does it shed any light for my original issue (invisible output in xterm)?

Sorry for mixing things up.

Just to make sure, you always restart the X server between building a Mesa
commit and testing xterm against it, right? And you're making sure that the X
server picks up your self-built radeonsi_dri.so for glamor?

If so, since that commit doesn't seem to affect the xterm issue, let's assume
for now that it's separate. Please file a new report about the GTK issue, also
against radeonsi, with the information from git bisect.

[Bug 110214] radeonsi: xterm scrollback buffer disappears while paging up/down

[bugzilla-daemon]

[-- Attachment #1.1: Type: text/plain, Size: 1095 bytes --]

https://bugs.freedesktop.org/show_bug.cgi?id=110214

--- Comment #27 from Diego Viola <diego.viola@gmail.com> ---
Actually, about your question:

> And you're making sure that the X server picks up your self-built radeonsi_dri.so for glamor?

I'm compiling Mesa in my home directory with the following configure switches:

./autogen.sh --enable-gles1 --enable-gles2 --enable-glx-tls
--with-egl-platforms=x11,drm,wayland --with-dri-drivers=radeon
--with-gallium-drivers=radeonsi --enable-debug --enable-autotools
make -j8

export LD_LIBRARY_PATH=/home/diego/mesa/lib
export LIBGL_DRIVERS_PATH=/home/diego/mesa/lib/gallium

So I assume this should make the X server pick the radeonsi_dri.so from
/home/diego/mesa/lib/gallium right?

I looked at the ~/.local/share/xorg/Xorg.0.log but it's not so clear:

[   437.304] (II) modeset(0): [DRI2]   DRI driver: radeonsi
[   437.307] (II) AIGLX: Loaded and initialized radeonsi

Is there a way to verify beyond this which radeonsi driver it's using?

OK, I was able to install Mesa system wide, glxinfo tells me this:

Mesa 19.0.0-devel (git-8daf5bb209)

Which is the commit prior to the bad commit I mentioned above.

Sadly xterm is still breaking as usual, the output disappears as I Shift+Page
Up and nothing changed in that regard. :(

I can reproduce this on Fedora 29 (workstation), I don't think the problem is
Arch Linux specific.

- XTerm(334)

Doubtful, environment variables from the user shell aren't propagated to the
Xorg process for me (which makes it very mysterious how LIBGL_ALWAYS_SOFTWARE=1
could make any difference...).

What if you install Mesa 18.3 system-wide?

Unfortunately that's not the issue, llvm-libs 8.0.0 just landed on Arch Linux
[extra] repository and the issue still persists.

Has Mesa been rebuilt against the new LLVM? Check the glxinfo output.

Something really funny is going on.

I've compiled Mesa 18.3.0 and installed it system-wide and that works (xterm
scrollback is fine with this).

I've compiled the latest Mesa git HEAD and installed that system-wide, this
fails.

Bisect time.

I'm afraid this is a red herring: as you can see from looking at the commit, it
simply adds new API with no actual user.

Are you sure? I've compiled the previous commit and that makes it work.

commit ee7f848c000112a98e9614f42921b176be473792 (HEAD)

Should I restart the git bisect?

Here's the current glxinfo output with the stock mesa on Arch.

[Bug 110214] radeonsi: xterm scrollback buffer disappears while paging up/down

For some reason glxinfo reports mesa 19.0.0 (stock package on Arch) after I've
installed mesa system-wide (18.3.0).

I didn't use a PKGBUILD and installed mesa by doing a `sudo make install'.

Maybe that's why the bisect went bad?

I know using a PKGBUILD is the right way to do it, but the last time I tried to
use it I got some conflicts with libglvnd when I tried to replace the Arch
Linux mesa package with the custom one.

OK, this one is also weird, I've compiled mesa-18.3.0 in my home directory,
exported these two variables:

export LD_LIBRARY_PATH=/home/diego/mesa/lib
export LIBGL_DRIVERS_PATH=/home/diego/mesa/lib/gallium

I startx after that, glxinfo reports the right mesa version (18.3.0) and lsof
says this:

$ sudo lsof | grep radeonsi_dri.so

But then I cannot reproduce the bug anymore.

Any ideas?

Xephyr.trace

Here is an apitrace to reproduce the bug, I used this:

export MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage"
apitrace trace /usr/bin/Xephyr -glamor :1 -screen 1024x768

As described here: https://github.com/apitrace/apitrace/wiki/Glamor

I can replay it with either of those commands:

eglretrace -w Xephyr.trace

or

glretrace -w Xephyr.trace

This was iive's suggestion (thanks).

That's likely one reason at least. At this point it's probably best if you
double-check everything before testing anything. :)

The working hypothesis is that it's a Mesa regression between 18.3 and 19.0, so
that makes sense?

Sure, sorry about any possible false-positives that I might have provided by
accident.

Yes, is there any more info that I can provide that you think would be useful?

It's probably worth trying git bisect again, double-checking at each step that
you're testing the right thing.

Sure, I think my attempt from #c47 should have allowed me to reproduce the
problem, I wonder why that failed.

I will try again.

I tried again and I can't get to replace the system mesa with my own build
because of some conflicts with libglvnd, and when I compile mesa in my home
directory and export LD_LIBRARY_PATH and LIBGL_DRIVERS_PATH to my mesa build,
glxinfo reports the right version of mesa and links to the libGL from my build,
but lsof shows the libGL from libglvnd is being used.

I contacted Thomas Dickey (maintainer of xterm) and he said this about the
issue:

drivers, or Xorg in general -

for instance the parts painting by XCopyArea
(used by xterm and some other applications)
may not be getting repainting-events

I restarted the bisect and ended up at the same "bad commit":

If I do this:

$ git revert -n 621b0fa8922ade0a8122b868177308e65e6d3595

Then xterm works fine and I still have direct rendering.

I just want to retract myself from saying these commits caused the problem for
me, sorry about that.

As suggested by MrCooper, I've compiled/installed mesa to /usr/local and added
/usr/local/lib to /etc/ld.so.conf.d/mesa.conf to override the system mesa.

We found that xterm still has the issue with Mesa 18.3.0.

We found quite a few things during our research:

export MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier"

This helps alleviate the problem (xterm does not have the issue with this),
however, the problem is still present in Xephyr.

We tested Xephyr from the current git master down to Xephyr from xserver 1.16
and the problem is also present, however, setting the following environment
variable:

export R600_DEBUG=nodpbb

Makes the issue disappear entirely.

To clarify, you mean Xephyr from xserver 1.16 here (where glamor didn't make
use of GL_NV_texture_barrier yet), disabling GL_NV_texture_barrier helps with
current Xephyr, right?

It seems like DPBB needs to be disabled when glTextureBarrier(NV) is called,
otherwise primitives may be reordered across the barrier. Does that make sense,
Marek?

Yes, that's correct.

If I set `export MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier"
` before running `startx`, xterm works fine either in X or Xephyr (from git
master).

Just to make it a bit more clear:

If I set that environment variable while I'm already on X:

export MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier"

It has no effect on Xephyr (from current git master), i.e. xterm still shows
the bug.

However, if I set before `startx`.

It works with both, X and Xephyr (from git master), i.e. xterm works fine.

xterm still shows the bug in Xephyr from git if that environment was set later
(while X was running).

Works fine with both (Xephyr git and X) if the environment variable was set
before startx.

Please let me know if you have more questions.

Primitives aren't reordered with DPBB. Primitives can't also survive a barrier
with DPBB. DPBB has no effect on behavior, it just changes how PS wavefronts
are formed.

Did you set the variable before starting Xephyr though, so it was set in the
Xephyr process? If yes, that makes things confusing again, just when it seemed
like they were starting to make sense...

Is there any way that could affect the glamor shader which samples from one
area of a buffer and draws to another (non-overlapping) area of the same
buffer?

What is the reason for radeonsi disabling DPBB for blits?

As long as the blits are truly non-overlapping, DPBB doesn't affect it.

because it's not useful for blits and it might add latency because of binning.

That was a mistake from my part, sorry.

Setting 'export MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage"' after startx
still makes xterm work fine even after startx (from a running Xorg session).

export MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier" makes xterm always work

Can you double-check this with Xephyr, taking everything we've learned since
then into account, and if the same commit is identified again, file a new
report about it?

I found that a workaround for this issue is to add the following to my
Xresources:

XTerm.vt100.scaleHeight: 0.9

The default is 1.0 (which creates the problem), a value of 1.5 also makes it
work (although fonts look too wide then).

I found this information here:

https://savannah.nongnu.org/bugs/index.php?52165
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880407

Which might indicate this being a freetype problem?

No. If it was a FreeType problem, R600_DEBUG=nodpbb or
MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier" couldn't work around it.

Changing the xterm configuration just happens to avoid the problem somehow.

Presumably the GL_NV_texture_barrier extension isn't available with GLES2, so
this is the same as disabling that extension with OpenGL.

I found another workaround.

Edit xterm's util.c and change line 2161:

unsigned int h = (unsigned) (nlines * FontHeight(screen));

to:

unsigned int h = (unsigned) (1000);

i.e. increasing the h variable to a large enough number makes it work for some
reason.

I have the same bug with xterm and shift+paging.

Another similar bug.

or 'cat /etc/passwd'.

I can reproduce this, it happens for me with xfce4-terminal and also
gnome-terminal and most other VTE-based terminals.

I also noticed that setting R600_DEBUG=nodpbb and
MESA_EXTENSION_OVERRIDE="-GL_NV_texture_barrier" does not seem to help.

VDrawable is just a big number, so same thing as Comment 86.

https://gitlab.freedesktop.org/mesa/mesa/merge_requests/1554 has some fixes for
DPBB, might help for this as well.

Unfortunately it doesn't help, I compiled mesa to /usr/local (from his
dpbb_fixes branch) but the issue is still there.

Created attachment 144948
  --> https://bugs.freedesktop.org/attachment.cgi?id=144948&action=edit
comparison screenshot

It looks like a DPBB/scissor interation issue.

The screenshot on the left is a replay of a faulty trace with dpbb disabled.
On the right the same trace, at the same point but using dpbb.

The last executed commands are:
   glScissor(3, 3, 480, 144);
   glDrawArraysInstanced(GL_TRIANGLE_STRIP, 0, 4, 1);

As you can see, the purple area on the right doesn't honor the defined scissor
area.

I just pushed a new commit on the same MR
(https://gitlab.freedesktop.org/mesa/mesa/merge_requests/1554/diffs?commit_id=d25df1274ea48fa73b0d8b31558e2cebb0851015).

Could you test on your machine and let me know if it helps?
