[amdgpu] Firefox window is visually corrupted after upgrading to Ubuntu 23.04

[Nicolás Abel Carbone]

After upgrading from Ubuntu 22.10 to Ubuntu 23.04, every time I open firefox the windows is heavily visually corrupted. It seems to work fine under the corruption, but it is completely unusuable.

The tar version of Firefox works fine. In the attached screenshot you can see the snap version of Firefox (corrupted) and the tar version of Firefox (working fine).

I tried uninstalling (with --purge) and reinstalling and refreshing firefox to no avail.

All other applications, including 3D games, are working fine. I am using an AMD RX5500 with default mesa drivers.

Switching to the beta firefox snap channel solves the issue.

Status changed to 'Confirmed' because the bug affects multiple users.

The issue is intermittent. It happened twice for me after reboot, the first time on first reboot after upgrade to Lunar, then a few days later. On both occasions it disappeared after some time (tens of minutes), but I don't know what I did to fix it..

More info: The bug affect all snaps but not ordinary executables. All snaps launch distorted. After a recent reboot I tried several times to launch Firefox, every time the bug appeared, and all my tabs where unreadable. Then I started Thunderbird (which is NOT a snap) and clicked on a link in a mail so that a new tab opened in Firefox. Suddenly Firefox was normal, and all tabs (also the old ones) where readable just fine! Other snaps e.g. chromium still launches with the bug.
When staring the snap "openscad-nightly", the initial splash screen (Welcome to OpenScad) is normal, but when I click on e.g. "Open Recent" I get a distorted window.
So far I haven't been able to recognize any message on stderr that are common when launching snap programs, but there are plenty of apparmor="DENIED" in dmesg, if that's any clue.

I'd be happy to provide log files if someone has any specific request

I've seen the same issue when testing Ubuntu 23.04 on a recent Zen 4 CPU with embedded GPU (not my computer so I cannot give more details).

The funny thing is that Firefox is not the only application impacted: the Ubuntu installer (the new one using Flutter) also appears completely corrupted, making it impossible to install Ubuntu from a live USB. The installer is also shipped as a snap application.

[Tony Mansson (tony-mansson)]

This issue was fixed a couple of months later in a regular update. I'm on 23.10 now on the same machine and haven't had any problems with snaps since. The issue can be closed as far as I am concerned.

[Daniel van Vugt (vanvugt)]

Let's let it close automatically... if there are no more comments in two months.
