I'm forwarding this, then, to the devel list. As I said, we've seen some
issues with Wayland, though my sense is that these are Qt issues,
mostly, not LyX issues (though they become LyX issues, since we depend
upon Qt).

If you have an option to try other Qt versions, that also could be helpful.

This sounds like it could be a shortcut conflict. Some wm's capture
keystrokes and interfere with LyX's own capturing of keystrokes. There's
not much we an do about that---if we never see the keystroke, we can't
respond to it. Hard to know if that's your issue or not.
