Description Peter Hutterer 2013-08-26 05:39:40 UTC 
XIAllowEvents changed request lengths in XI 2.2. A client calling XIQueryVersion 2.1 is expected 

If a client registers for XI 2.1 is expected to use the original (shorter) request, a client for XI 2.2 is expected to use the new request length.

libXi decides the request length on the server-supported version, not on the one the client uses. This causes a BadLength error in the server.
