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).

Thanks for the bug report. This sounds like a kernel bug but are you able to provide additional photos of the bug under different conditions?
