[digikam] [Bug 328124] New: digiKam extremely unresponsive and slow (probably related to tags)

Bugzilla from kde-bugs@kristiankoch.com
https://bugs.kde.org/show_bug.cgi?id=328124

            Bug ID: 328124
           Summary: digiKam extremely unresponsive and slow (probably
                    related to tags)
    Classification: Unclassified
           Product: digikam
           Version: 3.5.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: Tags
          Assignee: [hidden email]
          Reporter: [hidden email]

Some weeks ago digiKam became extremely unresponsive and slow. It's practically
unusable. In addition, the software needs a couple of minutes to start and eats
quite a lot of cpu. One temporary workaround is to delete digikamrc and start
with a brand new config. However, after tagging some images or managing tags,
digiKam becomes unresponsive again. For example opening the tag sidebar takes
some seconds and if it's open it takes several seconds to select an image.

Here's strace output with old digikamrc:
$ strace -c digikam

Object::connect: No such signal
org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)

use, all queries will cease to work.

All that i can see is that something is broken on your computer, about network
file system share through Samba. Perhaps it's due to a system update...

It's not digiKam, just a side effect.

Check your system.

What makes you so sure that it's not a digiKam issue? The Samba error message?
That's easy resolved by installing samba (although it's not needed). But this
doesn't change anything regarding to digiKam's responsiveness.
Do you have any idea where to start searching? I attached the valgrind output
to start.

There is nothing to see in valgrind trace about your problem.

A detailled trace of digiKam started will be more instructive.

Look in this page about how to enable debug spaces before to run digiKam...

digiKam console output with debug statements

Note: The missing libkvkontakte is not the reason.

Switching the icon theme from Oxygen to another one (.nitrux for example)
somehow solves the problem. I don't know if this a digiKam or KDE problem.
However, digiKam is the program that is predominantly affected.

digiKam is not directly relevant of icon theme set in your KDE desktop.

The way to render application style (widget/icons/window decoration) is
relevant of theme. Oxygen style is the most complex with a lots of settings, as
OpenGL effect for ex.

I recommend to check advanced settings for this theme in KDE control panel and
check the results. Some effects depend of video card and quality of video
driver, which include time latency   ...

It's related to the ICON THEME, there are no further setting related to OpenGL
etc.

This issue returned in the last couple of days. Unfortunately, I can't tell you
what triggered it. Changing the icon theme did not fix it. However, after
reading the bugs #315574 and #307219, I saw that several of my tags had an
symbol with a question mark. Resetting all tags with this icon to the standard
icon improved performance significantly and now digiKam is usable again.

Note: Contrary to bug #315574 the performance issue did not only appear when a
sidebar was open, but all the time. I suspect that one of the tags with
question mark icon was in the list of last used tags (right-click menu).
Therefore, those bugs might be duplicates.
