Description Najjar 2015-10-03 22:13:52 UTC

When doing file operations, plasmashell uses CPU as high as 15%. Such as copying or moving a file across any medium or type of FS.

I use Dolphin as a FM, and the bug happens with files on a Samba share, or files on a USB (regardless of the FS), or even within the same partition or different Linux partitions.

I've also noticed that it happens (~8% CPU) when playing a video file (I use VLC) after such file operation (the operation is done when this happens).

I think it might be the progress bar in notifications, but I'm not sure.

Reproducible: Always

Can I have the output of qdbus org.kde.KWin /KWin supportInformation

Here you go: https://paste.kde.org/p9lrdfyyt

Similar issue here, 100% cpu usage (one core) while that animation is playing.

Note that while I have an optimus laptop, the nvidia card is disabled via bbswitch and nouveau/nvidia drivers are not installed, so I doubt this is related to 351888.

This is still an issue in the latest stable (5.5.5)

Comment 5 Najjar 2016-08-31 14:11:26 UTC

So I came back here to report that the latest version (5.7.4) still uses way too much CPU.
I also saw bug 366060 from a month back marked as Resolved without any type of clarification by the closer, or by the assigned person (Edmundson). The report was on version 5.6.5

David Edmudnson has to look at the logs he's requested. WAITINGFORINFO isn't on our part. (I realize that this is probably an automated reply, but nonetheless)

Thanks for the update, I've set this to REPORTED so it won't be auto-closed.

May be related to bug #373368
