Im currently running bazzite, but the flickering has also happened on OpenSUSE
Im running the games via Heroic and Steam, both installed via normal packages (no flatpak)
Running via Proton-GE latest (10-10 at this point)
Running on a 1080p 144hz monitor connected with displayport
I have a ryzen 5 5600x, rtx 3060ti
I will try using a Gsync Monitor, but if anyone has any idea I’m open for it
Edit: Thanks to everyone, changing the Monitor did the Trick. I had a MSI MAG271CR, which already has had problems randomly disconnecting from Linux, and not showing a picture again until I did some shinanigans changing the resolutions
I changed my Main Monitor to a (Gsync compatible) Acer XB270H A, and it has none of these problems
I have that issue sometimes even with older games or anything with 3D.
In KDE I hit META-F12 to disable to compositor and it usually does the trick.
