Fullscreen games freezing under Plasma 6 (Wayland)

(I wasn't sure if this would be better here or in Desktop Environments, apologies if this is the wrong forum!)

The title really says it all. After booting up Elden Ring, for example, the game acts as normal until the cursor disappears, at which point the game completely freezes while still running fully in the background. This happens with just about every game (except, oddly enough, Dark Souls Remastered) weather it's set to fullscreen or borderless fullscreen/windowed, and only on Plasma 6 on Wayland. Other DEs, such as Plasma on X11, and GNOME and even Xfce, when running in Wayland or X11, work flawlessly. Also of note is that the problem only occurs when more than one display is connected.

Even weirder is that the problem was fixed for a while with Proton 10, but a recent update to either it or my system seemed to unfix it.

I was shocked to see that not a single other post on any other site corroborated my problem, leading me to suspect that I have consistently been screwing up my Plasma configuration somehow.

Here's my system:
Host: ROG Zephyrus G14 GA402RJ Laptop
CPU: Ryzen 9 6900HS
GPU: Radeon RX 6700S/Radeon 680M
Kernel: Linux 6.12.25-gentoo-dist

If y'all need any more information please let me know - this is my first post!
