Fullscreen windows get weird colors

Hi, since a few Days now, I have had a problem on my cachyOS install.
Fullscreen windows suddenly had pretty weird colors/low gamma.

First I thought this may be a proton/game Issue, it only appeared in-game, not in menus smh.
But yesterday I noticed that it happens in every full-screen application, also vesktop and my browser.
Here is a comparisons:
(the first image is the one with wrong coloring)(It does not show up on screen recordings or screenshots, so I had to use my phone).

System Information:

 CPU: AMD Ryzen 5 7600X (12) @ 4.70 GHz

 GPU: AMD Radeon RX 9060 XT [Discrete]

 RAM: 30GB

 Kernel: Linux 7.1.1-2-cachy-os

 DE: KDE Plasma 6.7.0

 WM: KWin (Wayland)

This is quite annoying, so if anyone has a solution for this I’d be very grateful < 3

Edit:
Interestingly, my KDE Lockscreen has the same problem, but my sddm login screen does not!

I fixed it by switching from prefer efficency to prefer color accuracy in the display settings.

I updated my system today and now the problems with the “prefer efficiency” mode are gone too.
