P3Dv5 viewgroup screen switching flicker

[micschneider]

Hi, today I switched to P3Dv5. I am using a viewgroup. xml from Immersive Display and 3 projectors. In V4 everything was fine but now it suddenly happens that the center view is constantly switching the view from one to another. It start to happen when I change for instance weather trough my instructor station. But there are also other triggers when the views starts to mess up. Does anybody know a solution. I already deleted shader folder, switched threaded optimization off, deactivated full screen opti and so on.
Thanks
Michael
