Yes, but if you are thinking about some thread in that toolkit/windowing library getting stuck while others continue working, you can try starting Emacs in X synchronous mode (etc/DEBUG has the details), then Emacs will wait for each X call to return, and X will not return until the request completes. If you see the same problem in that case, i.e. some frame(s) become not responsive while others don't, it is almost certainly not an Emacs problem.
