Dell XPS 15 :: Some Programs Do Not Display Their Windows On QHD Screen

I have a new XPS 15 9530with a Quad HD (3200x1800) screen running Windows 8.1.The Quad HD screen obviously requires some new smarts to display application windows properly because not all applications handle it well. "Beyond Compare" is a severe case in point - it seems that icons in it's windows are displayed very small and text box lines are truncated vertically, so much so that the bottom half (or more) of the text in these lines cannot be read. I'm guessing this is a Dell driver issue because of the newness of these screens. I'm a software developer and use Beyond Compare all the time. In some cases I can't even change the settings because the setting screen in unreadable with this issue.

There are other applications that exhibit the same or similar problem. Visual Studio 2010 has some issues, but the main problem I have with it is that some drop-down boxes are displayed extremely small. At least they're readable if you get close to the screen!the MS Office products I use all the time (Word & Excel) don't show any problems, but I wonder why these are good and "lesser known" apps have problems inadequate testing?

I develop in a dual-screen mode with a Dell U2412M monitor and the "bad" windows on the laptop screen do not change their perspective when I move them across - although during the drag they show as very large windows on the second screen until the whole window is in the second screen and then it shrinks to an "expected" size. It is this behaviour in particular that leads to think it is a driver "bug" that might be causing the window display problem.
