I've a truly odd-looking issue with Cedega. It's only drawing the top-left 640x480 of whatever game I'm trying to play - no matter what 'Desktop' is set to in the config file. That will increase the size of the game's window, but not the size of the drawn image.
To see what I mean, look here for a screenshot.
The size of the actual window is (I think) 800x600, yet only 640x480 is drawn by cedega. Setting the size of the actual window to 640x480 doens't help either - same result, just without the black border. The drawn window doesn't resize to fit the actual window.
If I enable DXGrab so that the mouse can't go outside of the drawn window, I find that the mouse can't exit the 640x480 area.
Has anyone seen this before, or can suggest something to try to fix it? I've flipped some of the options in ~/.transgaming/config to see if anything obvious would do it, and have had no luck so far.
