--- Comment #8 from max@veneto.com 2012-10-06 04:39:29 CDT --- ClientSideGraphics=N in X11 Driver section does help, behaviour is good as before.
Sorry, but due to ubuntu 64 bit build problems, I've no time to do some profiling on it by now. If somebody knows a way to setup wine build environment on ubuntu 12.04 64 bit, I'd be happy to try it... but no chroots nor usb keys, it'll take too much time to have it working.
Ciao
