So, Recently I went to DST and noticed that I couldn't really see anything, as It was zoomed into the top left corner.
PS. I have seen the post about DS where it said to delete "Settings.ini", which doesn't seem to exist for DST. I saw that something called "client" and deleted that, as it looked like the settings. And, it did undo the fullscreen but alas, didn't fix the problem.
