Disable highlighting animation in AnimatedProgressBar

Hi,
I've upgraded to the latest version of the Ribbon and the Shared Library, and I've started to use the AnimatedProgressBar control.
First, it really looks great, congratulations on the good work!

Here is the minor problem I'm trying to solve: I have a window where I use a rather large number of these objects (previously I used normal progress bars), they are inside a listview and their value is fixed most of the time.

Sometimes the user performs some action and the animated progress bars in the listview are updated with a new value (all of them at the same time).
I noticed that when I have about 6 or more progress bars, things get a bit slow. I assume the highlighting animation could be the cause (I already disabled the "value animation").

I'd like to disable the highlighting animation (i.e. the gloss thing that periodically moves along the bar), also because it looks a bit heavy with several rows.

I know I can set the highlighting color to Transparent: this makes the effect invisible, but it's still slow (I suppose the animation is still being computed).

Is there a way to disable the highlighting animation?

Thanks!
Francesco
