Description TOM Harrison 2017-05-27 13:24:48 UTC

plasmashell often freeze in various operation like copy, move, delete.
recently freeze in on camera:// delete action, and move file by dolphin.

in move file situation. it will generate a progress bar which has nothing inside.
in delete situation. it just file operation notification causing plasmashell LAG.

Is there any progress about this, or how to workaround. It is annoy due to frequent happen. When it happened all action on plasmashell is not working.

Comment 1 David Edmundson 2017-05-27 14:05:17 UTC

Please give steps to reproduce and ideally a backtrace of plasmashell whilst frozen.

Comment 2 TOM Harrison 2017-05-27 14:19:33 UTC

1. connect phone or camera.
2. browse camera:// on dolphin
3. delete lots of file on that device.
4. it may freeze during deleting.

It did not 100% reproduce, but I has met frequently.

Comment 3 TOM Harrison 2017-06-10 02:31:11 UTC

I think I may found a possibility about freeze.
I found plasmashell will const execute plasma-changeicons in /usr/lib/x86_64-linux-gnu/libexec in ubuntu causing large cpu usage and causing freeze even I just copy a file, not change icon.
after rename about that file. the plasmashell will become normal.

Thanks for the update, changing status.

Comment 5 David Edmundson 2018-07-12 17:32:20 UTC

That makes no sense

the only thing executing plasma-changeicons is the icons KCM in systemsettings

Comment 6 TOM Harrison 2018-07-12 23:53:57 UTC

I also think so. Now the apt update will also freeze plasmashell itself. I did not know why.

Comment 7 TOM Harrison 2018-07-12 23:55:01 UTC

sorry  I mean apt upgrade. when install or update package. last time I notice seems cups update

Comment 8 Roman Gilg 2018-07-27 15:10:54 UTC

Sorry Tom, but this bug report is in general too vague to really pin point the issue at hand. If you find a reliable way to reproduce the issues you experience and can better narrow them down, pls reopen.

For example if plasmashell freezes, try to get a backtrace as David mentioned. Closing for now.
