We did see some issues with the NDI feeds of the camera in certain setups have this issue. The screen would blank out grey for a frame or 2 and then over the next couple seconds, fill the pixels back in with the image. 


This seems to have been fixed with the newest version of the NDI HX driver which can be gotten in the NDI tools download. We did work with Newtek and our own engineering team to address the issue and so far this fix seems to be working for most people. If you do not see this fix your issue, please get in contact with us so we can look into the issue further.
