I have a dual monitor setup and if I do something in my timeline my external monitor footage crops in for no reason and It won't go back unless I disconnect my external monitor from "playback" settings. It doesn't freeze or anything but it just crops in and it is impossible to work like this.
I have tried different monitors and done updates but it still is happening. I think it might be like 150% crop. Sometimes it won't crop in but sometimes it does very fast.
