When virtual desktop is enabled in Staging I receive

00e8:err:winediag:nodrv_CreateWindow Application tried to create a window, but
no driver could be loaded.
00e8:err:winediag:nodrv_CreateWindow L"The explorer process failed to start."

Not even winecfg is able to start.

This started happening maybe 2-3 weeks ago after one of the rebases.

Regression test points to the following commit in Staging:

winex11.drv: Listen to RawMotion and RawButton* events in the desktop
thread.

We still need to send "normal" input from the clipping window thread
    to trigger low-level hooks callbacks when clipping cursor. This is for
    instance used in our dinput implementation.

Tested with wine-8.10-103-g8d2de5dbe1f (Staging)
