As you can see, the UI elements have moved themselves closer to the middle of the screen for some reason. This issue also shows during loadscreens etc like this:

That screen was taken just as I was about to finish loading, thus its just black in the middle, but you can see the issue there around the edges etc. No idea what's causing this as it's an issue I've never had in the past. Any ideas?
