I found that after switching from AlmaLinux 9.4+Gnome Classic to AlmaLinux 9.4+Gnome Classic on Xorg
the GUI became stable without (in my understanding - a whole series of) periodically occurring errors.
At the same time, I do not see a decrease in the speed of operation for my tasks.
It is clear that this formally only applies to the hardware of my PC and the applications I use, but it may be useful for someone to try such a switch in other cases, if suddenly there are errors with GNOME classic.
