I also have some problems with flicker on XPS 13(9350), but my
flickering is only on the chrome viewport, when moving the mouse over
elements on the page that uses animations the viewport turns black(?)
for a short time(some ms).

The flickering started recently.

Not sure if this is related, but I just wanted to add it in case it is
helpful for someone.
