(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...

All that seems to do is force the game into windowed mode and cause heavy artifacting (using gamescope -f doesn't show the game at all, but it still seems to be running in the background).
