Hi!
I posted this on reddit and then saw that kde has a lemmy presence, so I am posting it here also, since I vastly prefer lemmy over reddit.:
Sorry if this isn't the right place, but I have no idea where else to ask, I tried asking at discuss.kde.org but got no answers.
I am using Arch with KDE Plasma and an Nvidia GPU, when I play Steam games almost all of them work flawlessly but...
When I try to play older games (like Shadowrun Hong Kong or the rereleases of Sims 1 and 2, or Civ 4 or 5), the graphics are all scrambled like this:

The funny thing is, this is a photo of my screen, if I use Steam to take a screenshot it shows up normally in the screenshot folder...

As it only happens on old games I am thinking those do something different than newer games, it doesn't matter what proton version I use and it only seems to happen under plasma.
Any help would be appreciated!
Plasma Wayland or Plasma X11?
Nvidia and Wayland still has issues, even though KDE is defaulting to Wayland. Personally I don't think Wayland is fit for purpose at present so I use X11. I have an Nvidia GPU (3070) and no issues with games including older games in X11.
Sorry, Wayland not X11. The weird thing is that it only happens with old games, I guess I could switch to X11, but I am pretty happy with Wayland otherwise. If there was any fix I could try I'd want to do that before switching to X11.
If you have plasma installed you already have x11 installed, so you should be able to switch to an x11 session on login even if just to test this without having to install anything else
