Bug ID: 457785
Summary: Kate is extremely slow to exit
Product: kate
Version: 22.04.3
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: aar...@doofus.org
Target Milestone: ---
SUMMARY
Whenever a new session of kate is started, exiting takes a significant amount
of time, often a minute or more. In this case I only have a single file open,
i.e. kate -n somefile.txt. The file is also typically fairly small, like a GIT
commit message.
The window on the screen closes quickly, as one would expect, but returning to
the command prompt is extremely slow.
STEPS TO REPRODUCE
1. Type kate -n somefile.txt
2. Quit kate
OBSERVED RESULT
When I quit the window closes right away as one would expect, however there is
a very long delay until Kate returns to the command prompt.
EXPECTED RESULT
I do not expect a long delay.
