Hi,

In gtk+-3.22, the Wayland backend tries to guess whether the application
wants to actually inhibit shortcuts (e.g. if it's a virtual machine
viewer or remote desktop viewer etc). It does this by assuming that if
you explicitly grab the keyboard only on a toplevel window, it
translates this into a "inhibit shortcuts" request which eventually
results in the dialog you see.

The way to avoid this is to not take a keyboard-only grab on a
toplevel window.

However, looking at the available gtk+ 3.22.x releases, it seems that a
the "toplevel only" restriction in the above mentioned guessing
machinery is not available in any release; so check whether your
distribution includes the patch "gdk/wayland: Restrict shortcut
inhibition to keyboard grabs on toplevels".
