Yes, there is a server bug here, having to do with your switching
from having Hint set in the normal mask to not having Hint set in
the grab mask.  If both were equal it would work OK.  Since you
want hints, you should continue to ask for them in the grab, and
all will be well:

                XGrabPointer (dpy, w,
                              True,
!                             ButtonPressMask | PointerMotionMask
!				| PointerMotionHintMask,
                              GrabModeAsync,	    /* pointer mode */
                              GrabModeAsync,	    /* kbd mode */
                              limit_window,         /* confine-to window */
                              None,
                              CurrentTime);
