Dupe of bug 58908, though it seems the solution from bug 58893 won't help neither here nor there.
The user that reported that bug reported that adding that XFlush worked for him, but it doesn't work here, not surprisingly. Seems another XFLush, somewhere near input handling should be needed. Not sure if the mix of poll and epoll can cause some issues.
edit: for some reason I read the 2 bugs as the same, so the first part of the post before doesn't make much sense.
