We have the exact same problem. And it seems like it's not only the collection view that gets bricked but everything else just like with the isvisible bug. If the app run into this other binding updates stops working.

Our app is totally broken with the last update.
Both problems might be related?

Feels more lika an Alpha then a production ready product.

Has been reported a couple of times now, see #8178 or #8135 might get fixed with #8136 but its not merged yet although its a fatal bug.

Closing this one as a duplicate for now.

If you're still seeing this issue once SR2 is released please let us know

I did find a work-around for this, at least it worked in my scenario. Use the dispatcher around setting the property that is bound to the CollectionView's ItemsSource. :)
