There's another patch you can try in PR 47124. It's a bit outdated
because cairo got updated to 1.12.6 in the meantime, the relevant part
is (sorry copy'n'pasted so whitespace probably wrong):

+    bzero (&ev, sizeof(ev));
     ev.type = display->shm->event;
     ev.drawable = display->shm->window;
     ev.major_code = display->shm->opcode;


Does that fix your problem?
