Comment(by dsd):

 The difference between xorg-x11-server-1.13.0-7.fc18 (old good version
 from build 13) and xorg-x11-server-Xorg-1.13.0-7.fc18.olpc1 (new buggy?
 version included in build 14+) is:

 Patch removed: [http://lists.x.org/archives/xorg-
 devel/2012-October/034229.html Xi: Call UpdateDeviceState() after the
 first emulated motion event]

 Patch added:
 [http://cgit.freedesktop.org/xorg/xserver/commit/?id=b4e44b285ed0eee1d06514215a4b01d54f40094b
 Xi: Set modifier mask on touch events]

 Patch added:
 [http://cgit.freedesktop.org/xorg/xserver/commit/?id=863f32c930d71073ee5f78452b78bd459d024867
 Xi: Update the device after delivering the emulated pointer event(#56558)]

 My understanding was that the patch we removed never went upstream, and
 was instead replaced by the 2 patches that were added (and are now
 upstream). So we will need Carlos Garnacho to clarify the situation here
 and/or figure out whats going on, if we have found a new bug.
