qt5 static 32 bit source build - app mainwindow wrong color

I did a static build of Qt 5 from git (Qt 5 5.0.2) on Linix Mint 14 32 bit. When I build my app using the static kit and then run the program, the MainWindow is a different color (darker) than the window in design mode. I'm using Qt 5 5.0.1. This doesn't happen on the same static build in 64 bit Linux Mint. Any ideas or solutions? Any help appreciated. Thanks.
