Appearance issue with Dropbox Qt client and Qt 5 SDK

Hello,

I ave noticed some issues with the appearance of the new Dropbox Qt client as well as the Qt 5.3 SDK (and any programs built with it) on two separate openSUSE 13.1 KDE x86_64 installations on a ThinkPad X230 and a Virtualbox VM:

Any help fixing this would be most appreciated.

Regards,

Dan
