Bug ID: 490419
Summary: Open/Save dialog changes directories very slowly in
xwayland
Classification: Frameworks and Libraries
Product: frameworks-kio
Version: 6.3.0
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Open/save dialogs
Assignee: kio-bugs-n...@kde.org
Reporter: mwo...@gmail.com
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
After my desktop has been running for some time (could be a day or two) the
native file dialog becomes very slow in xwayland. This is observable in any Qt
application running on xwayland when the file dialog is used. Opening the
dialog takes several seconds, mousing over or selecting a directory is also
delayed by several seconds, and changing directories is delayed by several
seconds. This adds up to a significant inconvenience when browsing around the
file system. I have tried numerous things to reproduce the problem but the only
thing that works so far is to wait and eventually the problem shows up.
Restarting kwin_wayland resolves the problem as does logging out and then back
in to the desktop. When the problem occurs non-xwayland file browsing is still
responsive. In addition xwayland file browsing is responsive when a non-native
file dialog, such as a gnome or gtk dialog, are used.
STEPS TO REPRODUCE
1. Open an application in xwayland that utilizes the native file dialog or run
dolphin with the following command: 'QT_QPA_PLATFORM=xcb dolphin'
2. If the dialog is properly responsive try again some time later.
OBSERVED RESULT
The dialog displays with a significant delay and changing directories is
significantly delayed.
EXPECTED RESULT
The file dialog should remain as responsive as it is when the desktop is first
started.
