I used X11 more often lately and faced the same bug, so it is not actually a Wayland only problem.
It seems the flash occurs only in the evening. So my guess is that the bug is related to the Night Mode of Gnome that randomly deactivates itself for one frame. ** Summary changed: - [regression] Full screen white flash from time to time with Wayland + [regression] Full screen white flash from time to time (Wayland and X11) -- 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/1765141 Title: [regression] Full screen white flash from time to time (Wayland and X11) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1765141/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
