Bug ID: 474423
Summary: Copying lots of files results in filenames being added
to Clipboard History; on Plasma restart, slow and lots
of RAM used
Classification: Plasma
Product: plasmashell
Version: 5.27.7
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Clipboard
Assignee: plasma-b...@kde.org
Reporter: gerbils...@gerbilsoft.com
Target Milestone: 1.0
SUMMARY
I was using Dolphin to move around a lot of image files using the clipboard.
(cut, paste, etc) I needed to restart Plasma for whatever reason, and on doing
so, Plasma was not only acting very slow, it was eating up gobs of memory. (up
to 32 GB!) After a bit of diagnosis, I eventually found that the clipboard
history in ~/.local/share/klipper/history2.lst contained a full list of all of
the files I was moving around. This in itself isn't a problem, but it seems
that when the Clipboard applet starts up, it attempts to thumbnail all of the
files all at once, resulting in massive slowdown and significant memory usage.
Deleting history2.lst allowed Plasma to start up normally.
STEPS TO REPRODUCE
1. Cut 1,000+ high-resolution images from one directory.
2. Paste them in another.
3. Restart plasmashell.
OBSERVED RESULT
Plasma's start is slow, the UI is laggy, and it's eating up gigabytes of
memory.
EXPECTED RESULT
Plasmashell starts up and does not use significantly more memory than usual.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo Linux 2.13
(available in About System)
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.110
Qt Version: 5.15.10
ADDITIONAL INFORMATION
There's a related bug https://bugs.kde.org/show_bug.cgi?id=466589 that mentions
a memory leak in QWaylandClipboard. I'm using Gentoo's qtwayland-5.15.10-r4
package, which has this patch already applied.
