Package: xorg
Version: 1:7.2-3

XRecordEnableContextAsync works well with lenny up to date (xorg 1:7.1.0-18) but not with sid up to date (xorg 1:7.2-3
) on the same computer.
XRecordEnableContext works on twice.


I attach a little piece of code that work on lenny but not sid.

If you replace XRecordEnableContextAsync with XRecordEnableContext and remove 
XRecordProcessReplies it work on sid too, but the record is synchronous now and cannot be integrated in an interactive gui app.

I'm not sure which of XRecordEnableContextAsync and 
XRecordProcessReplies doesn't do it's job correctly.


To reproduce the bug, build the code with gcc main.c -lX11 -lXtst, run it and move the mouse. if it work, it should catch the mouse motion and print it on stdout.

This works now according to the upstream bug.
