Hey, I'm messing around with the moi 4.0 trial and I can't get rid of this white border around my viewport, as seen here:


While this isn't much of a problem when it comes to using the app itself, it can get very irritating to look at after a while.
I can't seem to find any setting I may have messed up in the .ini or .css files to change/fix this. Is there a simple css property that I'm missing here? Any help would be greatly appreciated.
