Bug ID: 499806
Summary: Gwenview's Start a Slideshow context menu entry causes
Dolphin context menu appearance to be delayed in
presence of a large number of files
Classification: Applications
Product: gwenview
Version: 24.12.2
Platform: Other
URL: https://bugs.kde.org/show_bug.cgi?id=499551
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: andrea.i...@gmail.com
CC: elvis.angelac...@kde.org, rthoms...@gmail.com
Depends on: 499595
Target Milestone: ---
Create lots of files, size doesn't matter as long as they're a lot, e.g.
#!/bin/bash
mkdir -p /tmp/file-gen
dd if=/dev/urandom of=/tmp/file-gen/file-random-0.bin bs=4K count=1
iflag=fullblock
for i in $(seq 1 30000);
do
cp /tmp/file-gen/file-random-0.bin /tmp/file-gen/file-random-$i.bin
done
Open Dolphin and make sure the "Start a Slideshow" context menu entry is
enabled. If it wasn't, also make sure to close all Dolphin instances (since it
appears changing the context menu is only effective on new instances).
Browse to /tmp with Dolphin, then right click the file-gen dir to bring up the
context menu
Expected result: context menu appears in a reasonable time
Actual result: context menu takes more than 10 or 20 seconds to appear
Disabling the Start a Slideshow context menu entry causes the context menu to
appear instantly.
Useful info: a similar problem is also known for Ark's compress/uncompress
actions. So if disabling the slideshow entry (and restarting Dolphin) still
doesn't "solve" the problem, make sure to also disable those Ark's context menu
entries, too.
With the Ark entries TBH I only noticed slow downs when invoking the context
menu on a large file selection.
With the Gwenview entry the slow down happens in that case as well, but
crucially ALSO when just invoking the context menu on the parent directory.
