I have written a trial piece of code with multiple stages. 
Two clutter stages are embedded inside a top level gtk window using
clutter-gtk. 

We have two stage of dimension 240 x 100 each, placed with no overlap,
besides each other.
One stage does text animation and the other animates a few textures.
There is a visible performance drop in frame rate Vs having just one
stage.
I have tried using the same timeline for both stages too.

Is this drop in performance, expected? 

I guess multiple stages means twice the amount of book keeping, but if
the amount of animation and objects is the same, 
does using multiple stages cause a substantial performance hit? 

GL is in software using mesa.
