This is a graphics glitch that takes the form of a blue bar that obfuscates the bottom part of the screen, therefore covering the UI. It happens whenever I move my characters, but stops happening when they stop moving. I have tried disabling AA, disabling Vsync, windowed mode, and updating graphics drivers.

 

You can replicate this bug by moving your character(s). This bug only happens when they are moving, and stops when they are still.

This only happens while I am in 1440x900, every other resolution is fine for some reason.

Did you ever find a solution to this problem, I'm having the exact same issue.

I'm running the game at the same resolution, using Windows 8.1 on a Macbook Pro with an Nvidea 9400M.

I've had the same kind of problem, but it only seems to trigger occasionally after I alt-tab out of the game. The only way I've found to fix it is to delete that save file and start over.
