Attaching a screenshot showing some of the early symptoms (see the scrambled content of the terminal, the horizontal line, as well as the oddly colored apport tab in tint2).
Usually the effects are dynamic (e.g., an icon or some part of the window gets drawn, disappears, gets drawn again, ad infinitum), so a screencast probably could be more illustrative (if necessary, I can find out how to record one). ** Attachment added: "screen.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1925429/+attachment/5490892/+files/screen.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925429 Title: Flickering of the graphical environment (i915 [drm] GPU HANG) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1925429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
