Does it happen in the Wayland session? A little context: I have a laptop (AMD GPU/CPU) and a Desktop PC (AMD+NVIDIA), I use wayland pretty-much only on my laptop, however I use only x11 on my main PC. I tried wayland on it a long time ago, it didn't even seem to start, black screen, sddm didn't seem to "handover". I have just tried plasma in wayland, and it's much worse, looking at the FPS, when not moving anything, it goes up to 200-300. As soon as a start moving my cursor it seems, heavy drops, to 25FPS, with the difference to x11 beeing: 1: FPS is 5 frames lower when moving mouse 2: Cursor and whole system is a little unresponsive, with sluggish/laggy cursor. 3: framrate never seems to stay at 60 Changing compositor settings does not change anything, while x11 still somewhat works, wayland session is pretty much unusable for me right now. Thanks for the info. (In reply to Nate Graham from comment #3) > Thanks for the info. Please (if possible) let me know if I can give more info or logs etc. Created attachment 163051 [details]

I noticed the same kwin behaviour few days ago, probably after last Nvidia update (545.29.02). Everything seems to work fine but sometimes windows maximizing/moving seems choppy, i added kwin framerate counter effect and it shows 30fps Operating System: Arch Linux KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 Kernel Version: 6.5.11-lqx1-1-lqx (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 3600X 6-Core Processor Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 Manufacturer: Gigabyte Technology Co., Ltd. Product Name: B450M DS3H Can confirm the behavior on my install as well. KWin seems to randomly lock to 30 FPS with no clear indicator or reasons why, and this is verifiable with the KWin framerate counter. Tried Picom just for a few minutes, and it seems to work fine, so this definitely seems like a KWin issue itself, somehow. Started to notice the issue after the most recent NVIDIA driver update (545.29.02), could be the culprit but I'm not sure.
