 Posted: Fri Sep 27, 2024 11:58 am Post subject: KDE6 Performace Issues |
 |
|
Hi,
Since up upgraded to KDE 6 on my laptop I have lots of performance issues.
When a notification popup shows every other window locks up for ~2 seconds. Video also pauses in chrome.
Popup menus take ~2 seconds to show.
Altering window sizes and dragging windows around is slow and stuttery.
This happens on both the internal and external monitor.

I start kde with startx and have the following in .xinitrc
| Code: | #!/bin/sh
#xrandr --setprovideroutputsource modesetting NVIDIA-G0
#xrandr --auto
exec dbus-launch --exit-with-session startplasma-x11
#exec dbus-launch --exit-with-session startplasma-wayland |
Starting with the two xrandr lines uncommnted doesn't change anything.

If I set the following:
| Code: | __NV_PRIME_RENDER_OFFLOAD=1
__GLX_VENDOR_LIBRARY_NAME=nvidia |
X exits with a seg fault:

Back to the original problem...
If I don't have an java application, Intelij Idea, running I don't see any issues. Can drag windows, resize them, etc nice and smoothly.
As soon and I open Intelij Idea the issue is present.
Close Intelij Idea again and the problem is gone. |

Found the following link:
https://youtrack.jetbrains.com/issue/JBR-6830/Poor-performance-with-KDE-Plasma-6-X11#focus=Comments-27-10012573.0-0
Just adding -Dwatch.desktop.geometry=false to the VM options of Intelij Idea fixed the issue with the following caveat:
NOTE: -Dwatch.desktop.geometry=false will restrict the IDE capability to react to change of the desktop scale before the IDE is restarted. Until the KWin bug that bombards applications with hundreds of notifications about the change that didn't happen is fixed, this cannot be avoided. |
