Using KDE PLASMA on wayland with nvidia , system suddenly starts lagging too much , i have to use other tty to use killall kwin_wayland to fix it , cursor movement starts leaving a trail which if moved enough covers all the window with its icons of trails of cursor .

I have even set power-profiles from battery submenu in kde to performance and it happens during general usage 5 to 6 tabs in firefox , one terminal open and one vlc video playing .

System has enough RAM (16GB) and enough computing too (i5 9th gen)

Kindly tell all steps to fix this nuisance.

This is a combination known to have issues still. For some specific hardware it’s working fine and others not. You may have a more stable experience on X11. You can always try again in a few months and see if it’s any better.

Try a different kernel. The Clear kernel is aggressively optimized for performance on Intel hardware. It is not optimized for stability, and is not necessarily accommodating for mixed hardware types (especially when it comes to hardware configurations that deviate from Intel’s ecosystem). If you are having issues of any kind, this is one of the first things I would change.

^ This. There has been issues with kernels just prior to 6.10.7 (which also includes the prior LTS version; as the issues that originated from those kernel versions made it over to LTS at the time). A good number of people were having freezing (where REISUB wouldn’t work) or random reboots. I had the freezing issues, and one time KDE did have a hard time starting correctly even. The Zen 6.10.7 kernel seems great so far though :smile:

Be sure to try something that offers 6.10.7 (like Zen) or the most latest LTS (currently 6.6.48-1).

Okay
First I am going to switch to linux-zen and if lags dont stop then I will switch from wayland to x11

Lag and jittering have stopped since i went back to linux-zen and x11

linux-clear is not fit for daily use or has some serious bugs
