Using emacs in KDE wayland, with the pgtk build. On a low spec machine,
emacs is hardly usable in this configuration. The menu system (file,
edit, options, etc.) misbehaves. For instance, you position the mouse on
"buffers", but the buffers menu does not open. To get it, you need to go
on File and then slowly move right through edit and options.

On a high spec machine emacs is usable with exactly the same config (Amd 
ryzen 9 with amd graphics).

in X11 mode, emacs is fine on both.

Po Lu, any ideas or suggestions?

Is this specific to KWin and Emacs, or reproducible on other compositors
and with other GTK 3 programs also?

Ping!  Sergio, can you please answer Po Lu's question?

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

Sergio

Ping!  How can we make some further progress here?

Sorry for the belated response.  Thunderbird is unfortunately not a
"real" GTK 3 application, as it implements a custom GUI; rather I'm
interested in the behavior of the GTK menu bar widget under your
compositor, which is best tested with the `gtk3-demo-application'
program.
