Hi guys I recently installed endevour os endeavouros-2021.04.17-x86_64.iso using the online installer and with the KDE Desktop option. Upon install everything seems fine when using the breeze-dark. However I noticed a notification of kwin having a graphics reset everytime I wake up the system.
This issue is more prevelant if I use a theme that uses kwin’s blur effect in which the title bar and close, minimize, and maximize buttons will either become warped (very enlarged or significantly shrunk). Closing and repoening the affeced app windows seems to fix the issue but putting my computer to sleep and waking it brings back the issues. Another alternative I tried is running kwin_x11 --replace via kde shortcut (idk if there is a way to run this when waking up from sleep) which does resolve the issue.
As a more perminant resolution I did attempt to run nvidia-installer-check and got the following reply.
Your graphics card (id: 13c2) is supported by the nvidia-dkms driver. To install a driver for this card, you can use nvidia-installer-dkms.
I then ran nvidia-installer-dkms and rebooted after the script finished. On the bright side updating the drivers did help graphics resets and title bar warping. Unfortunately I noticed the blur effect was disabled after the update. I when renabling it I noticed kwin’s cpu usage starting to spike. On ideal it would consume 10-30% of my cpus and if I move any windows it can use 50-70% of cpu. Windows move ment became choppy and if playing any videos say from youtube in fire fox or a mp4 in vlc I noticed a high degree of stutter. I tried forced compesisiton piple in nvidia settings (no dice), I tried the anti tear guide in the arch wiki (no dice). Only rolling back the update with time shift seemed to fix the cpu but brought back the graphics resets.
At this point I’m kind of at a loss, before Endavour OS I used to use Manjaro and had similar issues with kwin (the title bar and graphics resets). Not sure if this is even an endevour os bug or if I should post the bug in bugzilla for kwin. Please advice and sorry for the long post
