I’ve been trying to play games while watching a video at the same time and it seems like no matter what I do fortnite shows up stretched.

Even if I open a different app and split screen and then switch to it, fortnite appears to open in the right ratio but then when it loads it is all stretched (menu and gameplay)

Any way to fix this? Stuff like this was so easy on my galaxy fold there is a huge learning curve with the open.
