If you're using X11, this might also be Bug 475468. See if turning off floating panels and adaptive transparency help at all.

I yes I am aware of that bug and I have floating panels off and transparency set to opaque already. I'm using Wayland and this stuttering was introduced in 6.1 and seems to be caused by the new Triple Buffering feature. I experienced similar issues with this and similar issues to Bug 488860 . Like the other bug, I also saw 'GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT)' in journalctl. KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1 also fixes all of my issues. My system is using an AMD iGPU to drive the display with and Nvidia 3080ti dGPU w/ 550.90.07 for render offloading. Before setting the environment variable the iGPU was maxing out and lagging the rest of the system, afterwards it was back to normal usage. Some games also had internal UI flickering. This is with Wayland and things seem to be worse at 155hz vs. 60hz. Hope this helps. Yes, seems to be the same bug more or less. Then it isn't restricted to Nvidia only, seems to happen with Intel too. *** This bug has been marked as a duplicate of bug 488843 *** |
