Black flashing is back. All Niagara systems are turned off. So I have no idea what to do now. If anyone has a suggestion that will solve the issue I’m prepared to offer a $200 reward. I’ve spent a lot of time on this and its holding me back in my work. I’m working solo so the only help I’ve got is online. I thought it was the Niagara systems but I’ve changed them all over to GPU Simulation and even turned them all off and the issue persists.
