"For more than three months I and many more users are experiencing a problem with Radeon VII!"
Correction - with Radeon VII and Vega 56/64 cards. It seems to potentially afflict all cards with vega architecture, but it's a driver related issue.
I had a Vega64 with the same problem.
I switched to a Radeon VII and I have exactly the same problem again, is that a joke?
This happens exclusively when browsing Google Chrome.
This issue still exists. Happens at pretty random times, sometimes in game, sometimes while browsing, sometimes during mining. Only occurred for me once every couple hours, until today my pc just went bonkers and everything was blinking like crazy even after multiple restarts. And then while I was afk for a couple minutes the issue just stopped and everything went back to normal. I'll try to install the old 22.214.171.124 drivers later, to see if that helps.

AMD driver 19.5.1
The latest driver release notes (19.5.2) has moved the VII flickering from know issues to fixed issues! I'll be trying it out as soon as I can tomorrow. Has anyone confirmed this driver fix yet?
Edit: the frequent flicker is gone, but has been replaced with an occasional very large flicker/artifact
Can also confirm working on my end. It's been a little more than "a couple" weeks but I'm glad everything is finally resolved. Finally, we can go back to maxing games and browsing Chrome without massive tears. Have a fantastic weekend everyone.
Unfortunately, it's not entirely fixed for me. It's WAY better, but I still get occasional flashes of black or yellow horizontal lines across the screen. Yellow on the desktop with everything minimized, black when using a web browser.
