R9 380x Fullscreen Horizontal Lines Flickering

Question asked by derang on Feb 2, 2020


I recently noticed that i get weird horizontal flickering lines when i play games in fullscreen mode. Sometimes even the whole screen will flicker. The weird thing is that it doesn't do that in windowed/borderless mode. I'm using the latest drivers, which is the Adrenalin 2020 Edition 20.1.3 version.

I first thought it would be a high FPS issue, because im using a 144hz monitor, but even limiting my frames to as low as 60 FPS it still flickers. Also i tested my DP cable, by switching to another monitor and using 60hz and a DVI cable, but the issue persists. Already reinstalled the drivers multiple times with DDU. Does anybody know why it does that? I also have uploaded 3 images where the issues is shown in Counter Strike Global Offensive and a short video for Darksiders 2 Deathinitive Edition.
