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-X, which is subscribed to mesa in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
