First of all, I know xWayland already does this when in a Wayland session but RPCS3 (PS3 emulator) runs disgustingly bad inside Wayland on my PC, and during an Xorg session the same emulator runs perfectly, and it’s not a FPS issue or framerate, it is a problem that any game is simply unplayable because it suddenly gives stutters that do not exist in Xorg.
KDE Plasma honestly feels extremely buggy and slow on Xorg and so I don’t want to use Xorg, I would like to use Wayland and not have to log into an Xorg session every time I want to use RPCS3.
Now, I am using KDE Plasma 5.27 with Wayland and using Nvidia proprietary drivers (515).
(If Linux4Noobs existed on Lemmy I would have posted this there)
Try with:
env -u WAYLAND_DISPLAY appname
