It looks like the remaining flicker could be at least two different issues:
* gnome-shell often misses the first frame, leaving mutter to display a blank background: https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1102 Unclear if that fix is mandatory for this bug. * Asynchronous logo loading, so painting the first frame doesn't wait for it to be loaded. Good news at least I can't find any problem with mutter. It's all gnome- shell. ** No longer affects: mutter (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1867133 Title: Ubuntu logo vanishes and fades back in (with a slightly different size) on gdm start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1867133/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
