After using GNOME 43 Xorg with Debian Bookworm 5.19, I rebooted into Ubuntu 22.04 Xorg 5.15, did some checks and found out that on my Ryzen laptop this was caused by the amd_pstate scaling driver which lowers the minimum CPU frequency down to 400 Mhz instead of the 1400 Mhz default on the acpi_cpufreq which Debian uses.
Debian (acpi_cpufreq) behaved perfectly on both Xorg and Wayland, so I enabled the amd_pstate scaling driver and this issue came up the exact same way as in Ubuntu: it seems that scaling down a much lower cpu frequency and then back up all the times can cause some performance penalties and glitches. To me it's fine because in the Xorg session I disabled the animations and the battery life is noticeably better with the amd_pstate scaling driver, but as usual ymmv! -- 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/1969140 Title: Window minimize animation flickers and appears in the wrong place in Xorg sessions To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1969140/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
