Problem

I updated to Ubuntu 18.04, and I'm facing tremendous screen flickering/shaking/distorting at random times for random duration.
The display is working fine on another Monitor that I have.

Best Answer

I was observing screen flickering but not shaking. I had to edit my monitor config and change the framerate. By default mine was set to 60.169086456298828.

open terminal and run the following:

gedit ~/.config/monitors.xml

edit this line:

<rate>60.1690864562988</rate>

set it to be lower than 60 as mentioned by 4levels, I used 59.96.
