Plasma 6. Higher CPU/GPU usage

07 June 2024, 18:46:53

Hi there,

I used to use KDE Plasma until version 6 released. Stopped doing it mostly because of freezes. With this kind of problem, I’ve had to use another DE’s, that don’t fit my needs, and put up with their limitations.

So I tried Plasma 6.05 and was glad about freezes being fixed, but noticed higher CPU/GPU consumption under light workload. Playing YouTube video with Firefox takes up to 20% of CPU with 40% of GPU load. So does mpv playback. Both pieces of software are using hardware acceleration. This behaviour occurs under both sessions X and W. I also noticed higher GPU usage when just moving Dolphin window across workspace. Can’t figure out what could’ve caused such a problem. At first I thought that it might be linked with mesa or intel drivers, but such a problem doesn’t come up with others DE’s.

I saw someone complained this when using Ubuntu 24.04 recently on another forum.

You wrote what bothers you about KDE, but you ‘forgot’ to mention the criteria you used to make your choice.

Claiming that all other options are ‘not good enough for you’ doesn't really make sense.

I just pointed out that have had to use other DE’s because something’s wrong with Kwin. I thought if someone had the same issue, their might be willing to suggest a workaround.

Whom are you even talking to?

If you want to try finding the source, then look at what processes and services are running and sort by usage. "High" is also relative to your hardware. I use plasma 6 on runit and don't notice anything, but my hardware is a 7900XT and 5800X3D. There could also be configurations resulting from theming and animation settings that use more or less CPU/GPU, different distros may configure the desktop effects differently as well. One thing I did to conserve VRAM for LLMs was setting my wallpaper to a solid color and disabling most desktop effects, and it probably has an impact on the baseline GPU usage as well.

Apparently you still haven't understood that it's your duty to read up on what you're dealing with, it's definitely not my job to explain it to you in detail.
