Okay. I removed the code because my understanding of the comment was
that it was needed to prevent a hang during the busy wait for
visibility. Therefore, when I removed that busy wait, I thought that
poll_for_input_1 was no longer needed either.
However, from what you say, it sounds like it's rather needed after
creating a frame, unrelated to the waiting per se. I don't really
understand what the code does, but I guess you could try putting the
poll_for_input_1 stuff back in either before, inside, or after the
x_wait_for_event at the end of x_make_frame_visible and see what
helps?
