Hey guys, I tried a way, but I'm not sure if I could Duplicate it, I toggled the switch as suggested by @
Shawn, but also got the result as @
Stigg but no change. So, I opened my usual video, from a non maximized folder, and it opened up to a full screen, so I paused the video, toggled it to a small window, and then pushed play again, and then just out of curiosity I pushed the button that is picture in picture (Play in Mini View), and now every time I open a video from a folder again, its in Non-Full Screen mode. (takes up about the same size as when I adjusted it before Clicking Play in Mini View.)
I found this post trying to fix the same issue, so after finding a possible fix I created an account for commenting this. Hope this helps you guys, and anyone in the future that Might read through the comments as well. Good Luck!
