Huge display problems with IsBoxer after patch

[Altsoba]

After the patch today (don't ask me why, don't know the relation...) the display is completely messed up when I launch the game with IsBoxer. Windows are totally distorted, like in a random pattern each one displays differently.

When I launch the client without IsBoxer everything is normal.
And I've tried using 5 different files that worked just fine yesterday before patch.

Help needed. Thank you.

EDIT: Created a new file quickly using the wizard and it worked fine. Guess some display options from yesterday no longer work today. Just wanted to know which.
