(SOLVED) Games flickering despite running fine on Windows
SOLUTION: Apparently there's some sort of bug in xwayland that causes Steam games to flicker, so "downgrading" to X11 solved it (for now). Now all I need to know is how to file a bug report for this.
I'm trying to set up a Linux install for my mom (Ultramarine KDE on Wayland), and all her (2) Steam games are flickering. I thought it was from fractional scaling, but that doesn't seem to be the case.
Her games don't flicker on Windows, and I've already tried multiple versions of Proton. I'm not quite sure what's happening, and any help would be appreciated.
Specs
OS: Ultramarine Linux KDE Edition
Host: Dell Inspiron 15 3511
CPU: Intel Core i5-1035G1
GPU: pretty sure it uses integrated graphicsapparently it uses Nvidia? First time I've seen that, gonna have to remember that in the future. Both Linux and Windows are using integrated graphics with no sign of Nvidia anywhere??
If you need any more information, please ask me
Edit: other than the flickering, her games run perfectly fine.
Edit 2: Just learned my mom's laptop model has a discrete Nvidia GPU, gonna troubleshoot that in a bit.
Edit 3: Her laptop doesn't seem to have anything Nvidia inside, despite the fact that the Dell website says her laptop should, weird...
If it's that kind of flickering on KDE 6.X on Wayland that forced me to temporarily move back to Cinnamon on X to play Elden Ring again, it could be related to KDE enabling Explicit Sync by default and the NVidia drivers < 555 that don't support it.
It was only flickering, the framerate was fine.
After I installed the 555 driver from the repository, the flickering in KDE on Wayland was gone.
