SUMMARY
I can't reproduce this issue consistently, but it occurs often after the
following steps.
STEPS TO REPRODUCE
1. with Dolphin, create a new folder and open it
2. press F4 to open the Terminal panel and create 10,000 files by running the
following command:
$ for i in {1..10000}; do touch $i; done
3. create a subfolder
4. move hundreds or thousands of those 10,000 files to this subfolder (with
keyboard shortcuts or drag-and-drop)
OBSERVED RESULT
plasmashell process causes high cpu usage while the files are moved, and Plasma
is slow until the cpu usage decreases to the normal level. Please se the
attached screenshot showing the high cpu usage.
EXPECTED RESULT
plasmashell process with normal cpu usage and performance while the files are
moved
