I was working on a video today and decided to restart my computer because it was running slow. After the reboot, when I opened the project it was displaying the video twice, side-by-side. I think it might be in a 3D mode. It is doing this to every single project, even ones I haven't touched in months. How can I disable this?
I'm using an Intel Core i5-4590 CPU @ 3.30GHz with Windows 10 Pro.
