Screen recording of workspace switching
Here is a screen recording. Even thou i did "unpin" all icons today i did not manage to get it back to completely snappy. But the increase in lag, after i pinned some apps, is visible.
cannot reproduce here. Operating System: Arch Linux KDE Plasma Version: 5.18.0 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1 Kernel Version: 5.5.2-arch2-2 OS Type: 64-bit Processors: 2 × Intel® Celeron® CPU G1820 @ 2.70GHz Memory: 7,7 GiB of RAM Works for me too. Till, please re-open if it happens again in Plasma 5.18. Thanks! Still happens the same way in 5.18.0, still lots of CPU usage and then the taskbar updates. I tried to recreate it with pinned apps and without any pinned apps: * With all apps pinned (about 7) the lag was about 0.75s (this is a fresh session, it gets longer the longer i work) * i *unpinned* all but one app: the lag was about 1.25s * i unpinned the last app: the lag is now about 0.1s Looks like an old issue. Setting it to needs more info.
Please try with a newer version(plasma 5.23.5) and if this is not an issue any more let us know.

There is still lag and quite a CPU spike of the plasmashell-process, but even with some pinned Apps it maybe 100ms.
So it is not really annoying any more.
But i have since switched to a faster CPU (2012 Athlon → 2020 Ryzen), so that skews it maybe.
So from a user perspective it would be ok to close the bug. But if devs want more info what might cause that, i would like to contribute to that.
Cheers!
That's good to hear. Still, there is clearly a performance bottleneck somewhere here. It should be instant. It is for me. No further reports. Let's close it for now. |
