Screen Tearing doesn't work in Plasma (Wayland) with nvidia gpu

Issues & Assistance
1

I’m running CachyOS (driver version: 575.64.03, kernel: Linux 6.15.6-2-cachyos). Despite having the latest updates, I’m experiencing persistent screen tearing, especially in games and videos. I’ve tried enabling nvidia-drm.modeset=1, tweaking KWin compositor settings, and forcing full composition pipeline, but the issue remains. Has anyone successfully fixed tearing with nvidia on Wayland in CachyOS? Any specific configs, kernel parameters, or environment variables that worked for you? (I used a translator so there may be some inaccuracies)

2

Do you have the “screen tearing” option disabled in Display Configuration?

3

Are you using vsync in the games? Which frequency is your display running at?

4

No, I don’t use VSync in games, and my refresh rate is 75Hz

5

I have this function enabled

SOLVED: IT’S A LINUX KERNEL REGRESSION, NOT A KDE ISSUE. Roll back to the LTS kernel.
