Can't reproduce this bug with AMD. Disabling "Force (Full) Composition Pipeline" in NVIDIA settings and exporting KWIN_TRIPLE_BUFFER=1 seems to lower the usage spike significantly. OpenGL 3.1: ~10% OpenGL 2.0: ~10% XRender: <2% (These are measured in KSysGuard, Process Table, "CPU %" without dividing by number of CPUs) Unfortunately the lag is still there with OpenGL, although less severe. Using XRender makes it nearly unnoticeable. Okay the lag is still there, I guess it was a placebo. I enabled do not disturb forever, now it doesn't lag but I can't see incoming notifications :/ This bug was reported against an outdated version of KWin. We have made many changes since the. If the issue persists in newer versions can you reopen the bug report updating the version number. |
