Hello,
I have a RadComboBox (from the Q3/2013 release) with say 10 items and I am using the Windows8TouchTheme. On my win8.1 tablet the scrolling of the dropdown list is very (very, very) slow, when I swipe over the items. First nothing happens, then it scrolls a few items down or up. When I swipe over the scrollbar the performance is normal as expected.
Any ideas?
Erik

Yes, the issue can be observed in your wpf examples too. Maybe not such as extreme as in my app, but the scrollbar is always much faster and the swipe over the items is not fluid.

My test tablet has an Atom processor, so far below yours from a performance view.
The standard wpf combobox works like a charm on this tablet, so it's a bit surprising that the RadComboBox has such issues...
