Thanks for testing :)

I am on Fedora-16 with gtk-3.2.0-1 using the gtk3's default theme I
can easily produce several seconds of "after-scrolling",
however I have a large monitor (1920x1200). gtk2 is gtk2-2.24.6 with
"Mist" theme.
Both results are not good, even with gtk2 I can't just grab the slider
and scroll without stuttering (which works with Java and QT),
however with gtk3 its a lot slower. How much is hard to quantify
without frameworks available to measure.

Your CPU is about ~50% faster than mine - probably that's just enough
to not let scroll-events queue up?

Thanks, Clemens
