I thought this was a memory leak at first - still might be. But the Editor Loop swells after less than 45 seconds of gameplay and grinds the whole thing down to single-digit FPS. This is just with the camera running - I'm not even providing any inputs. This is a consistent problem that happens all the time, since I first reported it and the details on this thread: https://forum.unity.com/threads/really-awful-editor-memory-leak.1291532/#post-8188401 What is causing this behavior? I don't think it's a custom editor script as I'm not using any (to my knowledge). All my packages are up to date. Already tried a clean reinstall - no luck. Unity is currently completely unusable in this state.
