Title:
[comet lake] Screen is scrambled/distored and flickers
Status in linux package in Ubuntu:
New
Bug description:
The screen is distorted/scrambled every now and then. That is, it's
like a few lines of pixels are repeated (so it's a normally a blur).
The screen also flickers at times. This happens a few times a few.
I've noticed that if I close the lid and let the screen
dim/blank/suspend then normally is goes back to normal when it wakes
up.
To my knowledge his happens irrespective of what programs I use at the
time.
Dell XPS 13 (7390).
