So whenever I use a chromion based browser (edge, chrome and so fort) I get allot of flickering and flashes. Firefox no problems.
Just drag the window and lots of flickering or when watching movie content like youtube etc.
It can even let the AMD driver crash somethimes because of this.
This happened as well with a Nvidia card I have but this got fixed just recently by Nvidia but it's the same deal with my 6900XT card.
[Ampere] Chrome/Edge may experience random TDR while browsing 
Time for a hotfix from AMD as well..
