I was having an issue with lacking memory. Window's resource monitor told me that Display Fusion was using over 10GB of my 16. Unfortunately, I didn't have it configured to log anything or it got deleted when I shut it down, so I can't give that data. I have a pretty good suspicion though that it has to do with the window location feature. This is because over the last few days I've been running a batch file to open and close a game a few thousand times (...I really want that acheivement XD) and every time I've had Display Fusion move it to my second monitor and minimize it.

I'll experiment and run the .bat again to see what happens.

Nope. If it happens again, I'll attach the log.
