SUMMARY
Triggering a notification from dolphin (e.g. by compressing something with Ark) logs the following errors to the journal:

19.02.25 09:20	dolphin	qt.qpa.wayland: Creating a popup with a parent, QWidgetWindow(0x60e075e8e8a0, name="Dolphin#1Window") which does not match the current topmost grabbing popup, QWidgetWindow(0x60e076bba5f0, name="DolphinContextMenuClassWindow") 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.

19.02.25 09:20	kwin_wayland	kwin_core: Cannot grant a token to KWin::ClientConnection(0x644f09e601e0)


STEPS TO REPRODUCE
1. Compress some files from Dolphin using the context menu
2. A notifcation pops up stating that the task was finished and times out
3. Check the journal

OBSERVED RESULT
The above error messages appear in the journal.

EXPECTED RESULT
No error happens / error messages get logged.

Can confirm this warning, here's how I can repro it 

1. open dolphin in terminal, then open hamburger menu
2. go to create new and wait for the context menu to appear
3. right click the folder view
4. go to create new again

warning pops up

If you do steps 3 and 4 after restarting dolphin (and dont do 1,2)
the warning does not popup.

One variant of that is now fixed with

https://invent.kde.org/frameworks/kxmlgui/-/merge_requests/284

For more I think we need a Qt fix

https://bugreports.qt.io/browse/QTBUG-137467

This is now fixed in Qt and will release with 6.9.2 and 6.10.
