Seems like you are using a scaled view in your QGV-based code. You do 
not want to do this on X for an action game, as everything will slow 
down considerably. Instead, try doing what other games (like KBlocks) 
do: recalculate your scene size and elements, and always keep the scene 
and view in sync, without scaling.
