qt.qpa.wayland: No shell integration named "xdg-shell" found

[mattias-aims]

Bug description
Both the UI and the CLI tool print error messages on startup, however, they do seem to work anyway.

qt.qpa.wayland: No shell integration named "xdg-shell" found
qt.qpa.wayland: No shell integration named "wl-shell" found
qt.qpa.wayland: No shell integration named "ivi-shell" found
qt.qpa.wayland: No shell integration named "qt-shell" found
qt.qpa.wayland: Loading shell integration failed.
qt.qpa.wayland: Attempted to load the following shells QList("xdg-shell", "wl-shell", "ivi-shell", "qt-shell")
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found.

How to reproduce
Start the UI or CLI tool.

Expected behavior
No errors / find the correct integrations it needs.

Hi @mattias-aims

Try to run pgModeler from console using "-platform xcb"

I'm still having issues with deployment for Wayland.

[rkhaotix]

Alternatively, run pgModeler like this

QT_DEBUG_PLUGINS=1 ./pgmodeler

Put the full output here, please.

[mattias-aims]

Thanks! Do these error messages mean that there is something that is not working as it should or does it manage to sort it out in the end so that all works anyway?

[rkhaotix]

Hm.. the application is working even with these messages? If so, that's interesting.:)

[mattias-aims]

Yes it works as far as I can tell. Both UI and CLI tool to export SQL and PNG.

Here is the debug as requested of a startup of the UI then immediate shutdown:
