Despite I am not getting this strange things, in any case, this would be a
problem of _that widget_, and not of setting scrollperpixel property. In that
case, we should fix _that widget_ and they way it draws those items (a way I
never liked BTW).
About the flashing thing... I am also not getting this issue, but you can test
that flashing effect with Dolphin, plugin selector, etc. Was that a blocker ?
I mean, this flashing effect (if exists, would be problem of the widget itself
too). However, when you move like crazy the mouse up and down on an alternate
background it is normal that this happens, I don't see the issue. Much more, I
don't see your point on this statement.

Scroll per item has serious implementation problems, and I really didn't see
the exact point of this.
Imagine your item is bigger than the viewport, for instance. You also can find
similar problems when using this approach.
However, I think saying 'the implementation is not usable' because of one
widget (which always have been behaving pretty strange, 10^6 times slower than
the rest on resize operations, for instance) is pretty much hardcore.
I would say that the add applets widget is nice, but needs some reworking from
my honest point of view.
