This sounds like bug 1754284 so I will mark it as a duplicate until
proven otherwise. The workaround for that would be to select 'Ubuntu on
Wayland' on the login screen.
If you disagree with this then please run the following command to
collect more information:
journalctl -b0 > journal.txt

Title:
LInes/Flickers occur in upper half of the screen.
Status in xorg-server package in Ubuntu:
New
Bug description:
Lines or flickers occur in upper half of the screen while playing
videos(1080p).I think some frames are being dropped. Had the same
problem with Ubuntu 18.04. I think this is some issue with Intel HD
Graphics drivers in the system.Ready to do any follow up procedures.
Earlier when I used Ubuntu 16.04 there was no such problem.
