Sorry for the delay, I haven't had time to work on this until today.

mem=32G did indeed work to prevent the bug with the 6.4.x kernel, but of course
halved the available memory.

The new kernel you built also results in a correct display at idle. I saw in
the patch notes that it may result in problems under memory pressure, but it
sounds like there's work ongoing on the problem.

I wonder why the problem doesn't occur when using XFCE window manager if it's a
kernel/display driver issue at root.

Thank you very much for your help. Do you want to collect any more information
about this from my system?
