Attempting to stream with GPhoto and ZWO. Both drivers present a black frame while the FPS counter suggests incoming frames. Since it it with both cameras I feel it is less likely an issues with the specific drivers or settings but something deeper.
Edit. In addition while GPhoto driver is streaming the amount of memory it is using gradually increases. It is a though it is caching the frames. The ZWO camera does not display the same memory use.
