One thread use the XDrawPoints function to put pixel to the window. An other thread waits with XNextEvent for an event. Every time I produce some events the program stops. Reproducible: Sometimes Steps to Reproduce: 1. translate the xcb_Test.c with gcc -o xcb_Test xcb_Test.c -pthread -I/usr/include/X11 -lX11 2. run the program xcb_Test 3. to tap some keys Actual Results: Every time I produce some events the program stops with xcb_lock.c:33: _XCBUnlockDisplay: Assertion `xcb_get_request_sent(dpy->xcb->connection) == dpy->request' failed. or xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request))
= 0)' failed.
In the xorg-x11-libX11-7.4-1.29.src.rpm is the file xcb_lock.c.
