Bug ID: 470620
Summary: Clipboard filled with image URIs can cause severe
performance problems
Classification: Plasma
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Clipboard
Assignee: plasma-b...@kde.org
Reporter: annasonoh...@gmail.com
Target Milestone: 1.0
SUMMARY
The clipboard can cause plasmashell to use a lot of disk transfers and memory
if it is filled with lots of image URIs
This persists across system restarts, until the relevant images are removed.
May be related to the previews.
STEPS TO REPRODUCE
1. select around 50k images in dolphin
2. press ctrl+C
3. wait a few minutes. I/O usage and memory will increase over time.
OBSERVED RESULT
8GiB of memory, some more in swap, 100% disk read, plasmashell freezing, other
programs encountering long disk waits
EXPECTED RESULT
Some sort of cap prevents the system from becoming unusable
