Description

I'm running Xubuntu 12.04.1 LTS on an Asus T91MT "netvertible"; it uses a propietary mutitouch touchscreen. The "Mouse & Touchpad" settings in Xfce lists it as "Asustek, Inc. MultiTouch".

The touchscreen is fully working in all sorts of usages, even the multitouch gestures; but i can't "touch" the window borders in any way (moving, double-clicking, clicking on the buttons to close/maximize/etc.).

It's very likely another instance of this problem:

... but i can't understand Olivier's suggestion about "adding traces" fully and/or how to research it further. I'll provide further data if requested; i don't know where to look or what for.
