Hi,

Sounds like Intel driver issue.
Try to add xorg configuration and see if it helps.

You can just create a file like 20-intel.conf on /etc/X11/xorg.conf.d

Section "Device"
       Identifier "Intel Graphics"
       Driver "intel"
       Option "AccelMethod" "sna"
       Option "TearFree" "true"
       Option "DRI" "3"
EndSection

And login again, or mightbe reboot.

Best,
