and experience random crashes in the display. Either X11 terminates and puts me back onto the login manager, or X11 terminates and colorful blocks of pixel soup appear on the screen. Keyboard input will not be processed on pixel-soup, so I cannot fall back onto getty, I need to reboot.
It can happen with the internal and external monitors, with and without a dock. It happens once a month on office workflows and every few hours on OpenGL workflows. Software like a FDM-printer-slicer or a game or hardware video decoding (mpv --hwdec) can trigger this bug every few hours.

without any change to the crash frequency.
I would like to stop the X11 crashes, I may sacrifice hardware acceleration and battery efficiency.
