            Bug ID: 108194
           Summary: Civilization VI - Animated leader characters small
                    black squares artifacts
           Product: Mesa
           Version: 18.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

Created attachment 141871
  --> https://bugs.freedesktop.org/attachment.cgi?id=141871&action=edit
A leader character covered with multiple small black squares

See the attached picture. 

I'm not sure if the problem is related to bug 108111 so I prefer opening a new
one. If both are related to a LLVM regression it's possible we'll be able to
close both.

Computer info:
OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10, DRM 3.23.0,
4.15.0-34-generic, LLVM 7.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.2.1 - padoka PPA

This is actually another issue than bug 108111: I upgraded from Mesa 18.2.1 to
18.2.2. bug 108111 is fixed, but the characters are still displayed with these
small black squares.

I couldn't reproduce. Do you think you could get an apitrace [1] of the
problem?

Also if you were able to test 18.3 that would be great too.

It's also possible this is another example of bug #104602

--- Comment #4 from Hadrien Nilsson <freedesktop@psydk.org> ---
I'm not sure for bug 104602 as everything else renders correctly.

---------------
I installed a fresh version of Ubuntu 18.04 on a specific disk and added padoka
unstable ppa for mesa. I got this version:

1:18.3~git181021202700.2d235d6~b~padoka0

And the bug is still present. I also installed Ubuntu 18.10 (kernel 4.18), used
the stock mesa (18.2.2), and the bug was there too.

---------------
I have two concerns about apitrace:
  1. the apitrace file will be full of copyrighted assets. Isn't there a legal
risk to share such a file on the Internet?
  2. Civilization is a huge game and I'm afraid the apitrace file will be huge
too (I need to reach the Leader screen before stopping the recording). What is
the best way to share huge apitrace files with Mesa developers?

---------------
Maybe I could also enable some kind of error logging, or a dump of compiled
shaders? By the way, the rendering level for Leaders is set to "low".

I'm back on my daily installation, with Mesa 18.2.3. In case in can help, here
are my LLVM versions:

ii  libllvm6.0:amd64            1:6.0-1ubuntu2        amd64        Modular
compiler and toolchain technologies, runtime library
ii  libllvm6.0:i386             1:6.0-1ubuntu2        i386         Modular
compiler and toolchain technologies, runtime library
ii  libllvm7:amd64              1:7-2~oibaf~b         amd64        Modular
compiler and toolchain technologies, runtime library
ii  libllvm7:i386               1:7-2~oibaf~b         i386         Modular

Possibly related to bug 104602. Can you try the workaround from that bug
report.

To be clear. Can you right click on the game in steam, select properties.

Then click 'Set Launch Options'. In here add: R600_DEBUG=nir %command%

Click ok, and close the properties window. Then launch the game.

--- Comment #7 from Dieter Nützel <Dieter@nuetzel-hh.de> ---
If I read this right Civilization VI in an OpenGL game?

Without shifting the focus to much have anyone maybe set EQAA filtering?
I've found an EQAA regression with TGSI and NIR running DiRT Rally on our
Polaris 20.

Same corruption.
unset EQAA helps, here.
I've did some testing for Marek and Nicolai in April/May/June 2018 and have now
to bisect.

I started both Steam and the game with R600_DEBUG=nir, it has no effect on the
bug.

Graphics settings are all either "Low" or "Disabled", with the exception of
v-sync. This includes anti-aliasing (thus no EQAA).

My system was slightly upgraded to kernel 4.20 and Mesa 18.3.3 (the bug is
still here and looks the same).

Do you think you can test git master now that this fix [1] has landed?
