Poor FPS/Performance of editor unless two editor windows are open?

Just updated to Unity 2019, imported a project I've been working on recently and went to play test - getting less than 30fps. I opened another editor, created the same scene, dragged in my scripts - 100+ FPS. Closed the previous window (poor fps) and when I went to play test the newly opened editor, it now was suffering from the low FPS. Opened another editor and reopened the project again, play tested - 100fps.

What did I break? Has anyone else experienced this? I don't want to have two editor's open to develop my games lol.

Fixed? I did a bit more digging, and found something that seemed related and gave it a shot - I switched my project Graphics API from DirectX 11 to OpenGLCore. I'm not sure if this is so much a fix or a bandaid though?

Hopefully someone can provide an answer that helps me understand this a bit better.
