My Xorg.0.log is full of errors like this:

And dmesg seems to contain more information:

I have attached full logs: dmesg.log (125.3 KB) Xorg.0.log (15.5 KB)
I have 2560x1440 monitor attached (actually it is 1440x2560 rotated with xrandr, I used suggestion by NVidia employee here 1440x2560 HDMI display not working - #3 by WayneWWW to fix hdmi2.0.c and recompile the kernel; I did not do any other changes to the kernel).
After a while, Xorg freezes and uses about 100% CPU. Any ideas if this is hardware or software issue? The monitor works fine with NVidia card on my PC (GTX 2060 SUPER 8GB) and even with Raspberry Pi, so I guess monitor’s hardware is OK.
