Graphical glitches with Mesa 21.0.3 on AMD Radeon RX 5600 XT

[Mateusz Stachowski]

[Impact]
The new upstream version 21.0.3 has a regression on radeonsi (amdgpu), which shows as graphical corruption on the desktop apps with certain hardware.

The fix is to add a commit from upstream staging/21.0 -branch, which never got released as 21.0.4.

[Test case]
Install the update, use desktop apps, see that it works correctly now.

[Where things could go wrong]
The fix adds a single line for an earlier commit that was incomplete. In theory it might regress some other amd hw, but this is highly unlikely.

Since the update to Mesa 21.0.3 I have graphical glitches in desktop: Unity, Gnome Shell both sessions (X.org and Wayland).

Also most of the programs have glitches. However Firefox seems unaffected.

please give the latest focal live image a go:

http://cdimages.ubuntu.com/focal/daily-live/current/

since impish live image worked fine according to bug 1925320, I'm hoping this one is fine too

[Timo Aaltonen (tjaalton)]

hmm so it was impish which was fine, test hirsute too :)

[Mateusz Stachowski (stachowski-mateusz)]

I've checked the latest focal live image and it has the exact same glitches as my install.

[Mateusz Stachowski (stachowski-mateusz)]

Hirsute live image works without problems.

That has mesa versioned as 21.0.1. So it looks like the problem is in 21.0.3

[Mateusz Stachowski (stachowski-mateusz)]

I've found that other people with RX 5600 XT had problems with this version of mesa.

https://bugs.archlinux.org/task/70554

https://gitlab.freedesktop.org/mesa/mesa/-/issues/4691

There is a new release of mesa (21.0.3-2) that fixes the problem for those users.

Hope that you upload it to focal-proposed.

[Timo Aaltonen (tjaalton)]

yes that looks to be the one.. I've pushed the fix for hirsute here:

https://launchpad.net/~canonical-x/+archive/ubuntu/x-staging

please test, and I'll backport it to focal too

[Mateusz Stachowski (stachowski-mateusz)]

But I didn't had problems with hirsute LiveCD.

And my install is focal.

I've tried the ppa with release changed to hirsute but focal can't be upgraded due to conflicts.

[Mateusz Stachowski (stachowski-mateusz)]

I used the hirsute LiveCD again and it has mesa 21.0.1.

I refreshed apt but there wasn't any update of mesa. So I enabled hirsute-proposed and upgraded mesa to 21.0.3.

Then I logged out and straight away there were glitches on the login screen. I've logged in and confirmed that Gnome Shell and programs now also have graphical glitches.

Then I used the ppa and it solved the problem. So I confirm that the fix works.
