Hi Carsten, this is strange. I'm running not exactly the same example that I sent you but the changes I made to simplify shouldn't have any bigger impact. I started to investigate the error in detail and this is what I got up to now:
- if I start only the client and 1 server no crash happens - if I start more than one server the crash happens after each start - your guess was right, one of the TileCameraDecoratorPtr::dcast() calls in MultiDisplayWindow::serverRender() failes, the one in line 244 - the cast failed as serverWindow->getPort(sv) is a ProjectionCameraDecorator; sv=2; serverWindow->getPort(sv) is of type FBOViewport clientPort->getType() is of type Viewport Does this help? Any Suggestions?
