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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1934783 Title: Graphical glitches with Mesa 21.0.3 on AMD Radeon RX 5600 XT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1934783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
