Google Earth has this problem with its own, bundled copy of Qt.  If 
you're using Ubuntu's Qt libs, you shouldn't have this problem.

Do other Qt apps have the same problem?  Try "smplayer" for example.

Other than that, it could be a DPI problem.  What is your screen's DPI 
as reported by X11?  You can find out with:

   xdpyinfo | grep resolution

Try changing it to 96:

   xrandr --dpi 96

and then start the application again.  If that seems to help, you should 
configure X11 (or your graphics driver) to use a correct DPI.
