I really do not know where to start. As of late, I've had issues with KWin segfaulting a lot and now compositing will just stop working. All my desktop effects (Blur, Fade, etc.) will stop working, and I can't restart them without restarting the PC, and even then, that sometimes doesn't work.
Here's my system info. Plasma 5.10.3 and Nvidia 375.66. I've tried all compositing backends and none of them fix the issue.
