            Bug ID: 99330
           Summary: Severe flickering with Fiji on Wayland
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: vedran@miletic.net
        QA Contact: dri-devel@lists.freedesktop.org

I am using

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Fiji [Radeon R9 FURY / NANO Series] [1002:7300] (rev ca) (prog-if 00
[VGA controller])

on Fedora 25 running GNOME 3 with Mesa git and LLVM git on two 4K monitors.
When using Wayland, there is a noticeable flickering in the upper part of the
screen when switching between desktops. Nothing relevant is shown in dmesg.

Also, when using Xorg, everything works fine.

Would a screenshot be useful? Any other info I can provide?

I happen to have 2 4K monitors and a Fury as well actually.

I actually couldn't run Wayland at all for some time, perhaps it was fixed by:
mutter (3.22.2-3) unstable; urgency=medium

  [ Jeremy Bicha ]
  * Add git_flush_all_swap_notifies_on_idle.patch:
    - Add patch from 3.22 branch that fixes freezes with multiple monitors
      on Wayland
landing in my Ubuntu repos.

Anyway, today I can run gnome shell in Wayland and I don't have any flickering.

Do you have the very latest firmware from
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git ?

Guess the devs always like dmesg and xorg... wait nevermind that last part. :-)
Maybe journalctl /usr/bin/gnome-shell  ?

Wait, actually after some DPMS and

[ 4378.466834] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock

journalctl /usr/bin/gnome-shell now show a bunch of stuff like:

Still, this could just as well be a gnome-shell bug?

Does it work with an older mesa/llvm version for you?

That's also in Fedora as far as I can tell:
https://koji.fedoraproject.org/koji/buildinfo?buildID=823521

Mesa 13 and LLVM 3.8 in stock Fedora doesn't help.

Got it, thanks Ernst:

Jan 10 17:44:30 localhost.localdomain gnome-shell[22110]: Failed to flip:
Invalid argument

I also got the following in dmesg, but it's likely unrelated as I get it with
Xorg as well:

[Tue Jan 10 17:44:29 2017] [drm:amdgpu_crtc_page_flip [amdgpu]] *ERROR* failed
to get vblank before flip

Please attach the dmesg output, preferably captured after the problem occurred.

It might be related. There might be similar messages about the page flip ioctl
failing in the Xorg log file, Xorg might just be more resilient against it.

Somehow can't reproduce it right now. The only related package I see in my
today's updates is GTK3 3.22.6-2.fc25 [1] which fixes [2]. Could be that. Will
report if it happens again.
