Graphical glitches with Mesa 21.0.3 on AMD Radeon RX 5600 XT

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

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

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

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

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

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.

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

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.

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.
