I'm using a 2015 4K iMac w/ Intel Iris Pro Graphics 6200.

While viewing full screen Youtube and Vimeo videos in Chrome or Canary, videos will occasionally flicker/flash/blink a black screen.

This happens on both VP9 and AV1 encoded videos on Youtube. Happens even when there are no extensions installed.

On Chrome, the issue seems to go away when I disable hardware acceleration but then I notice performance drops. The issue also seems to go away when I enable "stats for nerds".

I haven't seen any flickering on Safari or Firefox.

Any thoughts on why this might be happening? Anyone else noticing the same issues?

I have reset the PRAM and SMC.

What OS are you on? 10.14? And do you have Microsoft Office installed?
