Problems NI Maschine 1.8.2 with Nuendo 5.5.5

I’m running Nuendo5.5.5 in 64bit mode and Maschine 1.8.2 in 32bit VST mode in Windows7 64bit.

Opening the surface of Maschine displays right, but if I move the mouse over the Maschine-surface it deletes the content of the Maschine userinterface.

If I run Maschine as standalone software everything is allright.

I do not know if this is an issue from Maschine or Nuendo. But I think it is no problem with graphicsdevicedriver as the standalonemode runs well.

Here is a screencast where you can see the behavior. The graphics is as shown it’s not caused by recording the video.

I also tried Cubase6 32bit and Maschine 1.8.2 in 32bit VST mode in Windows7 64bit. There was no problem.
So I guess it’s a problem based on Nuendo5.5.5 64bit.
