Public bug reported:
I am observing screen that my Dell screen flickers once in a while for a
short duration (about 5 secs or so) after upgrading to latest LTS. The
problem is 100 % reproducible on my computer by holding the left mouse
button pressed while dragging the scrollbar. Even otherwise this
flickering is observed automatically about 3-4 times in a span of 20
mins.
Expected Behaviour: The screen does not flicker automatically or while
scrolling a web page.
