Description Peter Hutterer 2012-03-20 06:20:27 UTC 
Description of problem:
The display member of XI2 events is garbage. The cookies themselves are fine, the actual event is uninitialised though.

http://cgit.freedesktop.org/xorg/lib/libXi/commit/?id=9419fe9f0b21232d342885a693fbf9222b5844e4

Version-Release number of selected component (if applicable):
libXi-1.3-3.el6

How reproducible:
Requires custom test program. select for XI2 events, call XGetEventData() on a cookie and then check the display member of the cookie data.

Peter do we have such program in hand?

cookie-display-check.c

This program fails with an assertion error if the error manifests itself. It requires human input (moving the pointer when prompted) to ensure a even is received and can be checked.

cookie-display-check.c

Updated for bugfix. mask.mask wasn't initialised, so depending on its contents the server may have replied with a BadValue error. Fixed by setting mask data to 0.
