(SOLVED) Games flickering despite running fine on Windows (lemmy.zip)

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 graphics~~ ~~apparently 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...

What kind of flickering? Does the display support adaptive sync? If so, try turning that off

I had the same issue on fedora KDE, and I fixed it by setting my framerate to 60 instead of 144 or disabling adaptive sync.

I don't get flickering from adaptive sync but my screen just goes black for a couple seconds every now and then when it is enabled, usually when playing. No idea why or if Windows would have the same issue.
