Sort of fixed.
Just to clarify the entire game slides right out of view as I move the mouse to the edge of the screen. This starts right from the startup screen with the circular logging in percentage thing. The game begins half of the screen.
Play windowed as big as it goes. Not ideal but it works ok.
When fullscreen, you see part of the game and you can "scroll" to other parts by moving mouse to the left/right/top/bottom edges of the screen?
If yes, then selected resolution for game is unsupported by video card and system is providing virtual resolution for you. If system is providing virtual resolutions to game, then this could happen.
If no, then no idea what the heck is going on.
