Project to Replicate the Issue
I have a Xamarin.Forms app that uses a ListView with an HasUnevenRows = true. The ItemTemplate of the ListView is implemented with a Dynamic View Cell where the Cell Height gets set OnBindingContextChanged.
As I scroll down through the viable sized list items the description text is missing on some of them (all rows have a description).
Scrolling up and down the list those that previously have description get their descriptions cleared as well.
As I scroll up and down the list the descriptions disappears on others, and so on.
I created a small project that has all the elements of my app and was able to replicate the same issue. Please see the attached project. ListView code is in the Views/NamedColorsPage.cs in the Portable project. Note that I am running on the latest Stable version of Xamarin.Forms 1.3.3.
Also note that this works fine in Adndroid and the issue is happening in iOS (both Retina 8.1 Simulator and actual device).
I have attached a video (screen movie of the simulator) to show the issue with the attached project. Also, attached is my XS info.

Screen Recording Showing the Issue
Please note too that this works great before the 1.3.1 update.
I checked this issue and I am able to reproduce this issue with Xamarin.Forms 18.104.22.16823 but after updating Xamarin.Forms 22.214.171.12429-pre3 and observed that it is working fine.
Please reopen it again if you are able to reproduce this issue with updated Xamarin.Forms 126.96.36.19929-pre3.

You will get the fixed patch very soon. Hopefully next week.
I have checked this issue with Xamarin.forms version 22.214.171.12432 and now its working fine at my end.
