There are some interesting PCI errors in your kernel log, which might be related. But if those are relevant then they would not be fixable in software. So I can't tell if this is a hardware issue, mutter issue, a kernel issue, a libinput issue or a Xorg issue. Please confirm again the problem does occur when you log into 'Ubuntu on Wayland' and run 'xrandr' after doing so. Then paste the output here.
