I never said anything about suspicious activity (and the idea that something 
could be wrong with Q*Animation on my systems didn't come from me).

You'll need a CPU-load measuring tool, of course (I used top, as mentioned 
previously, I'm not particularly interested in more advanced performance 

If animations run at 60Hz as you say, how do you explain that the app above runs 
with essentially the same CPU load on a 1.6Ghz N3150 and a 2.7Ghz Core i7? The 
latter CPU should spend significantly more time waiting to display the next 

I looked for a way to control the animation frequency but couldn't find one; what 
did I overlook?
