Thanks for the report, and glad you are enjoying it! I actually have a 2560x1440 monitor and haven't noticed it bleeding past the edges, although I haven't tested much in windowed mode admittedly so I will have another look at that. I think your bug report has narrowed down where the hang was occuring so I'll get to fixing that. I haven't experienced that personally in my testing. The campaign will definitely be rebalanced a bit shortly, expect a new build with bug fixes and balance updates in a couple of weeks.
