I'm still struggling to understand how gnome-shell is triggering the corruption. Maybe try switching between 42.5 and 42.9 a few times again and verify in both cases the mutter packages remain 42.9.
Also can you find any other app affected? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2026886 Title: [amdgpu] google chrome hardware acceleration broken on 42.9-0ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2026886/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
