These issues sound like a variety of issues that were resolved as part of Plasma 6.0.
Another thing that could also help is turning on NVK in Mesa (with updating to Mesa 24) and setting DRM_NOUVEAU_GSP_DEFAULT=y
in linux-current
when you upgrade to 6.8. As long as you have the latest linux-firmware along for the ride, you can completely remove the need for the NVIDIA proprietary driver for NVIDIA Turing and newer GPUs.
(Blame @EbonJaeger for me commenting there 😜 )
Update: Problem persists after updating to Plasma 6 via regular updates with the unstable repo
Please confirm there isn't an existing open bug report

Plasma Wayland had been very usable up until around June 2023. After an update, it became laggy. I hadn't reported this before because I had been doing testing of VAAPI / Firefox with Reilly and thought that might have affected things. Even after removing the vaapi package, however, the performance is still slow.
As a workaround I tried setting
KWIN_DRM_USE_MODIFIERS=0
in/etc/environment
as well asKWIN_DRM_USE_MODIFIERS=1
but saw no change in performance.Possibly useful logs attached
