Public bug reported:
As far as I know, this upstream bug fix for <a
href="https://bugs.freedesktop.org/show_bug.cgi?id=46976";>Xserver 1.11+
reports absolute valuator.values for relative devices</a> leaves some
wine games (and possibly other programs) with erratic mouse movement.
The patch is included here: <a
href="http://patchwork.freedesktop.org/patch/9595/";>dix: set raw event
values before adding up relative values (#46976)</a>. Any chance of a
rebuild including this fix?
Copy of patch (probably won't work unless spacing is fixed):
