Opening a Menu is very slow (if at all); closing it gives a Gdk-Message about a "temporary window"
TSIA. I noticed this while adding a ComboBox to testinfobar, but it seems to replicate everywhere I've tried that opens a menu (so testcombo, testmenubutton, the MenuBar in gtk4-demo, etc.)
Opening a menu takes about 1 second between clicking on the button and the menu popping up.
Worse, the "Looong" combo in testcombo seems never to open at all...
Closing the menu then produces this message in the console:
Gdk-Message: 19:05:43.732: Window 0x557137ff4690 is a temporary window without parent, application will not be able to position it on screen.
