In my system I have intel HD Graphics 620.
When I play video or drag any window I see the horizontal lines on the screen like slices. horizonal lines while playing video
I tried one solution. i have edited /etc/X11/xorg.conf.d
file content to
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
EndSection
after this, my issue is solved but I got green blocks on the screen every time I boot the system.
