Wayland is only a communication protocol between the app and the server. The underlying screen updates are implemented by gnome-shell (via libmutter) using KMS. You can make it log LOTS of information by adding this to /etc/environment:
MUTTER_DEBUG=kms If you do that and then record a separate log each time a flash happens: journalctl -b0 > anotherflash.txt then that might be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1948778 Title: Random flashes in gnome-shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1948778/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
