I will just paste the same text that I posted on reddit.

GPU: XFX RX 6600 XT

CPU: Ryzen 5 3600

Motherboard: Gigabyte B450 GAMING X

BIOS Version: F63b

RAM: 16GB G.skill ripjawvs 3600MHz CL19

PSU: Corsair CX750

Operating System & Version: Windows 11 Pro

GPU Drivers: Adrenalin 22.8.1

Description of Original Problem: I don't know if it's my gpu or monitor but sometimes my display "flickers" with weird artifact like lines. I had 2 RX 6600XT before, first was faulty and I got it replaced for the second one wich had the same issue wich at that time I thought was another broken GPU.
Then I bought the XFX card.

Here is an older video of the issue: https://streamable.com/589bns

Troubleshooting: Swapping DP cable didn't help, using HDMI didn't help, changing refresh rate didn't help, turning off FreeSync didnt' help, changing from windows 10 to 11 also didn't help. Before RX 6600 i had RX 480 wich worked fine, in the meantime I borrowed a 1080ti and it also worked fine.

So just to recap; all three of the RX6600 caused this exact issue, but the RX480 and 1080Ti did not cause this issue?

[Gozdiii]

Yes, first one was giving me proper artifacts in games, other two just these lines.

Is it only happening on one monitor? If 2 different cards are giving the exact same issue on only one monitor then the problem has to be the monitor or the cables or connectors, since you say you have already tried running it on DP and HDMI and the issue is still there, it's the monitor.

Yeah, the monitor is the main suspect right now. The only thing that is bothering me is that it started doing it now on a newer card. On my RX 480, it was running the same settings.
