I'm sorry, but this is not KWin related. If X consumes CPU, that's X's problem. If gwenview consumes CPU it's gwenview's problem. But not KWin's. It's not only gwenview. Resizing of any window leads to lags. I've tried livecd with GNOME and it's working fine. So I guessed that it's a KDE bug. I'll report a bug to Xorg as well. |
Starting from KDE5 windows resizing became a nightmare. Currently, while resizing the Gwenview window X consume a single CPU core completely leading to huge lags. GPU usage, according to nvidia-smi is 20-30%. There are no warnings/errors in /var/log/Xorg.0.log, dmesg, ~/.local/share/sddm/xorg-session.log. The only custom option is Option "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }" in xorg.conf From where can I start to investigate performance issues source? Gentoo Linux stable x86_64, KDE 5.10.5, i5 3570k@3.4, nVidia GTX 960 4GB (driver 384.90), 1080p monitor.
