On Ubuntu 20.04 LTS, the screen display causes Z distortion when playing a video or switching photos quickly after the screen is rotated. see the recording video. I also tried several tests but still no solution, such as testing different monitors, change the different video player(vlc/mpv) or modifying xorg.conf as follows
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "Tree"
EndSection
