Also strange - your screenshots show corruption which should only be relevant to mutter and the graphics drivers (kernel / mesa). I cannot imagine how gnome-shell is related. More like gnome-shell is triggering a bug in mutter, mesa, the kernel, or Chrome.
On the slight chance this is related to another AMD GPU issue I've heard about in 42.9, please try adding this to /etc/environment: MUTTER_DEBUG_USE_KMS_MODIFIERS=0 -- 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
