After commit 0b92da3 ("Process XKB events in loop") on xorg-server 1.19.0 (at least, others don't try) kbdd always on top and eat 100% CPU. Rolling back this single patch solve problem.

Fixed for me by changing "while(){}" to "do{}while()" in this place.

PS Now all fine, but googling also subject to future deep test: change XPending(display) to XEventsQueued(display, QueuedAlready) - blocking vs. non-blocking.
