The reason it uses XWindowCheckEvent is precisely to avoid blocking.

The thread putting buffers on the screen is trying to use that same X display
connection. It will be stalled waiting for the input thread whenever the input
thread is holding the xlock.

It might be possible instead to poll/select on the X display file descriptor
(XConnectionNumber()) and avoid using a timeout. It probably needs to be done
in a way that uses GstPoll(), and disables it when the display thread is doing
any X operations.
