You should be able to confirm that the server got a GrabPointer with
xmon. But I'm not sure if/how you can find out who sent the
GrabPointer request - it does mention grab-window but I don't know
enough about X11 to know how to relate that back to the application.

Sample output from xmon:
............REQUEST: GrabPointer
sequence number: 0049
owner-events: False
request length: 0006
grab-window: WIN 02800004
event-mask: PointerMotionHint | Button5Motion
pointer-mode: Synchronous
keyboard-mode: Asynchronous
confine-to: WIN 02800004
cursor: None
time: CurrentTime
..............REPLY: GrabPointer
status: Success
sequence number: 0049
reply length: 00000000

Good Luck
