Description

ListView items are disappearing and CollectionView items are swapping places.

I have raised them together due to similarites but can raise as separate if needed.

Steps to Reproduce

ListView issue, This is very easy to replicate and can be seen within 30 seconds

1. Create a list View
2. Add data of varying sizes
3. Scroll

Expected Result All list items are responsive and seen. Actual Result Sometimes listView items disappear and come back when scrolled away and back to.

CollectionView issue, This is harder to replicate and may only be seen every now and then but I have still noticed it multiple times

1. Create a collectionView
2. Add data of varying sizes
3. Scroll

Expected Result All collection items are responsive and seen. Actual Result Sometimes collectionView items appear as other items further up in the list and return back to their true state when scrolled away and back to.

Items are disappearing and appearing in ListView on Android as well. Dotnet Maui 8

[SamuelJames101]

@jsuarezruiz I have noticed this has an iOS tag but I now see this issue mostly on Windows.

Verified this issue with Visual Studio 17.10.0 Preview 3 (8.0.20). Can not repro it with sample project.

[SamuelJames101]

With the nightly build It seems to be working now on windows. Don't see the issue on iOS or Mac with the service release either.

@ewoody What platform are you seeing this on? ListViews or CollectionViews? And I can't see the video you have uploaded. Thanks

I would try a collectionView, ListViews were too broken for me to even use

[kevinxufei]

This issue has been verified for Visual Studio 17.10.0 Preview 6 (8.0.21/8.0.7). It can be reproduced.
