Description Chris Toshok 2012-03-20 14:41:20 UTC
mind you, I couldn't find docs/samples/blogs about what the values *should* look like, but these values passed to the method look sane for velocity, and insane for targetContentOffset:

velocity = {X=0, Y=0.7103275}
targetContentOffset = {X=-1.998565, Y=3.629363E-43}

that was for a sizable vertical flick of my thumb, so I'm not sure 1) why there's any targetContentOffset registered (the X velocity is 0), and 2) why the Y offset is so low.

marshaling/binding problem?

It definitively looks like a marshaling problem.
Comment 2 Rolf Bjarne Kvinge [MSFT] 2012-03-27 09:32:23 UTC
It was a marshaling problem.

Fixed in master (47ac894) and 5.2-series (13c33ae).

The next releases with this fix will be 5.2.11 and 5.3.3.
