Thanks. Is there anything special you do to reproduce the crash ?
(application, window manager,. specific input devices ... )
The XAllowEvent() call that seem to cause it is not used by any
application in base as far as I can see. So this code path in the X
server is not tested often, but this area got quite some churn during
the 1.20 -> 21.1 release cycle...
I am using xfce4. It crashes regularly when using Firefox along with
the mouse and scroll wheel.
