Does the workaround mentioned here https://github.com/stride3d/stride/issues/2008#issuecomment-2118869130 still make sense, it's probably best to remove or replace that workaround instead of adding another workaround because of that workaround ?

[Doprez]

I can remove it but it still happens from your original comment due to the IsFullScreen caught and ignored error.

@Eideren I finally think I figured it out. This seems to work for both the issues of fullscreen toggle AND exiting when in fullscreen. You were right it had to do with the Window events.

Im going to close this and make a simpler PR since the solution was just to add an event for specifically disabling the fullscreen
