Created attachment 40009 [details] backtrace with ddraw debug channel
I confirm this bug.
It must be noted that moving the mouse on the screen makes the display appears.
nvidia geforce 7600go driver 295.40
In my case, the mouse cursing isn't shown at all and moving/dragging/clicking the mouse doesn't do anything, but that may be another bug.
