Descriptive Problem Summary:

Part 1:
I wrote something to grab the players screen resolution and then increase the game's interface and map display to match the player's resolution. It's always worked perfectly without any issues. Sometime yesterday it stopped working. I didn't update anything and literally just ran the game. What happens now is that it grabs my resolution, it increases the interface and map output to match my resolution like it id before, but it displays the game as if it were normal. I've disabled letterbox and enabled it. I've tried old versions and still nothing. The biggest part of the problem is that it ONLY happens to me. I hosted a server and every single person that joined was able to view the screen at full screen, no matter their resolution just fine. But for me it still displayed as if I didn't put it in full screen despite the interface and map output stretching to match my screen resolution.

This is someone else's screen at full screen(ignore the text at the bottom): http://puu.sh/515Bd.png

And this is my screen at full screen(again ignore the text): http://puu.sh/51aj7.png


Part 2:
I've noticed something and I think it has to do with the same thing. A couple of people have sent me their projects where they set the interface's background color to something and then they set that color to be transparent. When I run a game like that, it opens fine. The problem with it is that the map output is completely black. The game is running and the map and all of the icons are there and the sound as well. But for me, it shows completely black. How do I know the stuff is still being shown somewhere? When I click and drag the game to another part of my window. The map output is "stickied" or "imprinted" on my desktop at the same exact spot that it was before I dragged the window. The map output is still black even after I drag it, but whereever I drag it. It leaves an imprint where it used to be.

So..This is what I see: http://puu.sh/51buF.png

And this is what's imprinted on my desktop after I drag the window somewhere else: http://puu.sh/51bvi.png
