Bug ID: 482890
Summary: Submenus popup don't show on Wayland QPA platform
Classification: Applications
Product: kdenlive
Version: 24.02.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: vhaudiquet...@hotmail.fr
Target Milestone: ---
SUMMARY
When QT_QPA_PLATFORM=wayland is set, which seems to be the case for me by
default (maybe since the latest update, or since i changed the QT wayland
plugins I use), it is not posssible to see the popup sub-menus (sub-menus of
file/edit/... like file->recently opened).
```
qt.qpa.wayland: Creating a popup with a parent, QWidgetWindow(0x616cf3bf5b40,
name="MainWindow#1Window") which does not match the current topmost grabbing
popup, QWidgetWindow(0x616cf58131c0, name="timelineWindow") With some shell
surface protocols, this is not allowed. The wayland QPA plugin is currently
handling it by setting the parent to the topmost grabbing popup. Note, however,
that this may cause positioning errors and popups closing unxpectedly. Please
fix the transient parent of the popup.
```
The error seems to be that a submenu popup sets it's parent as the main window
instead of the menu, which seems to be not allowed on qt+wayland. If I run
kdenlive manually setting the platform to x, I can see the popup menus just
fine.
This is for all the submenus of the top bar, file/edit/..., for example
file->recently opened.
STEPS TO REPRODUCE
1. Open kdenlive with QT_QPA_PLATFORM=wayland
2. Click file
3. Click 'recently opened' : no submenu opens
(this is just an example, any submenu will do)
OBSERVED RESULT
no submenu opens
EXPECTED RESULT
the submenu opens
SOFTWARE/OS VERSIONS
Arch Linux
Qt Version:
- local/qt5-base 5.15.12+kde+r151-1 (qt5)
- local/qt6-base 6.6.2-4
- local/qt6-wayland 6.6.2-1 (qt6)
ADDITIONAL INFORMATION
I'm using Gnome, and that might be part of the problem, although the log
doesn't seem to reflect that. If it is gnome-related, and that is an
unsupported use case for you, please let me know !
It happened just after I installed QGnomePlatform/... so maybe it is related,
but there also was a kdenlive update, so I'm not sure. If you can't reproduce
without that, I guess it is the fault of that package, which is i think
'deprecated' as of now, so I guess it will stay that way.
Thank you for your time and awesome work !
