I tested a little bit more with KBounce, and this seems to show that the approach through the plist file does not really
work for KDE applications. While setting QT_GRAPHICSSYSTEM in the plist file does not provide visible changes, 
launching it through the command line while having set export QT_GRAPHICSSYSTEM=raster beforehand completely 
changes the speed of the application.
