Comment 1 for bug 1956851

This fixed my issue on Intel UHD Graphics 620:

sudo mkdir /etc/X11/xorg.conf.d/
echo -e 'Section "Module"\n\tLoad "dri3"\nEndSection\n\nSection "Device"\n\tIdentifier "Intel Graphics"\n\tDriver "intel"\n\tOption "TearFree" "true"\n\tOption "TripleBuffer" "true"\n\tOption "AccelMethod" "sna"\n\tOption "DRI" "3"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf

Screen tear is gone and no artifacts
