Clipping can be disabled by setting "GrabPointer"="N" in HKCU\Software\Wine\X11 Driver.
Thanks for reply.
RegKey GrabPointer works, but select grab mouse by winecfg don't work too. My suggestion is: wine default disable grab mouse in virtual desktop, if user really need grab mouse just enable it by winecfg, so just need one regkey GrabFullscreen. This way is much more clearlly and simpler to an enduser who don't care about too much stuff.
