Bazzite makes one of my Monitors stroke out

Bazzite

I’m relatively new to Linux (dabbled with arch on my Laptop and had a Steam Deck for close to a year), but after installing whenever i get to the desktop one of my monitors starts bootlooping and the taskbar vanishes,it constantly makes the non-stroking monitor switch between the primary display and being secondary. Unplugging the screen that’s having issues is not helping.Both of my monitors are samsungs, one fhd and one qhd (qhd is the one having issues). this did not happen during installation, while i’m in the login screen or in windows (dual-boot).
Anybody have or had a similar issue or know a fix?

Can you confirm that the monitor doesn’t have issues on another OS?

Can confirm, worked flawlessly before I transistioned into the dual-boot setup on windows and it works flawlessly on windows now.

Could LACT be the issue? I don’t see how liquidctl or coolercontrol could be an issue, unless it caused a temperature issue.

Other than that, maybe it’s the HDMI? IIRC Linux as a whole still have problems with HDMI 2.1 right?

After fiddling around for a while i’ve found that swapping the cable types of my monitor seems to have fixed the issue. Changing from DP to HDMI seems to have stabilized it, while the other one on the same DP cable is still issue free. Very weird, but if it works, it works. At least it rules out the GPU ports themselves being an issue.
