bug#72549: 29.4; menus do not work properly on wayland (pgtk)

[Sergio Callegari <sergio.callegari@gmail.com>]

Sorry for the delay.

Unfortunately cannot try with other compositors, only kwin.

Other gtk3 applications are mostly fine. Note that on the specific 
machine many things are slow. For instance typing with thunderbird shows 
some lag and minor hangs. However, one thing is being slow, bothering 
but acceptable, and some other thing is becoming incorrect as in opening 
the wrong menu.

Thanks for looking into the issue
