Bug ID: 422306
Summary: Dolphin and KDE file dialogs open very slowly
Product: frameworks-kio
Version: 5.70.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Open/save dialogs
Assignee: fa...@kde.org
Reporter: bugreporte...@gmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
Dolphin, as well as KDE file dialogs in all KDE applications, open very slowly.
It takes several seconds for the file-open dialog to display in Kate or any
other application. Also, it takes several seconds for Dolphin to display any
window content on first opening.
After it is open, Dolphin does not have slow responsiveness (except as related
to Bug 393977).
STEPS TO REPRODUCE
On my system, the steps are this simple:
A. open Dolphin
B. or bring up the File Open dialog in Kate or any other KDE application that
uses KDE's file dialogs
OBSERVED RESULT
I have to wait several seconds before I see a file dialog appear, or before
Dophin shows any content in its window.
Even on a fast desktop system (such as a modern Intel i7 with NVMe disk and
plenty of RAM), there is a delay of several seconds before Dolphin will
populate the windows contents or before a KDE file dialog will open/display.
EXPECTED RESULT
No delay.
GTK file dialogs (on the same system running Plasma 5) open instantly. Dolphin
and KDE file dialogs should open almost as quickly. Other software on this
system is not slow.
SOFTWARE/OS VERSIONS
Arch Linux
KDE Plasma Version: 5.18.5 (from About System Settings)
KDE Frameworks Version: 5.70.0
Qt Version: Qt 5.14.2 (built against 5.14.2)
proprietary nVidia driver
HARDWARE
This is a modern desktop computer with Intel i7 CPU, fast NVMe disk, 32GB RAM,
fast nVidia GPU.
The hardware is not slow.
OTHER BUGS
I do not believe this is related to bug 169929 because once Dolphin in open, it
responds normally (except as related to Bug 393977).
It is also not related to bug 179955 because print dialogs open quickly. I only
see file dialogs and Dolphin having slowness.
