GridView Overlap Effect

I have a gridview with grouped data.

Everything is similar to the Grouped Items page template in VS2012, except that I installed more data than they are there (about 15 groups, only about 200 units).

Everything is fine, except for the strange effect of overlapping in the middle of the page. It is not always in one place. When scrolling this overlap area can move to other groups.

Here is a [screenshot] [1].

Any idea why this is happening?

I tried to reproduce the same problem in the project that I just created using the Grid App project template in VS2012. I copied my DataSource object there and everything worked fine until I did one small thing - set HidesIfEmpty = "True" for GroupStyle in the GridView.

Incredibly, this small option, which should help us hide empty groups, makes this weird overlap effect.

I bet it's because you insert ScrollViewers - maybe put some GridViews in a ScrollViewer or "master GridView".
