(Get the code!)
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 to 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!
