Title:
20.04 Screen tear when watching video
Status in Ubuntu:
Confirmed
Bug description:
running 20.04 on thinkpad t470, with "Mesa Intel® HD Graphics 620 (KBL GT2)"
graphics and gnome version 3.36.1. Whenever I am watching a video, on any of my
displays (laptop, or 2 external), there is a screen tear in the middle of the
screen. I have never experienced this before while I was using 18.04, and it
started immediately after installing 20.04.
