Test case & screenshots
Customer reports that UICollectionViewController does not work as expected with Xamarin.iOS current Stable.
> The last working version was the Xamarin iOS xamarin.ios-126.96.36.1993.pkg. All packages after that, does’t work or show[s] this problem.
> I used your ios-samples-master. SimpleCollectionView.
> If I scroll fast down and up, multiple times, the visible cells after scrolling are not well calculated or rendered. [I] don’t know where is the problem.
> I checked this on my physical iPad and also in the simulator. no differences. both devices have the iOS 10 Version.
### Expected results
Cells are uniform size after scrolling
### Actual results
Cell size is inconsistent, with some intermittently 2x-3x larger than others and/or missing image.
Downgrading from Xamarin.iOS 10.2.1.5 to Xamarin.iOS 188.8.131.523 did not seem to help.
iPad Air & iPad Retina simulators (both iOS 10.1) with XI 184.108.40.2063 appear to work OK
iPad Air 2 simulator (iOS 10.1, iOS 9.2) & iPad mini 2 (iOS 10.1) with XI 220.127.116.113 exhibit issue
Simulators running iOS 9.2 or 10.1 with latest Stable exhibit issue

I can reproduce this issue but going to an early version of Xamarin.iOS like 9.8 does not seem to help which suggest this is likely an issue with the sample
What means that? Is the problem my test case?
What should I do? There is no solution, and I need one. Because we are not able to release.
thanks for the support,
i found the problem alone
Was it a problem in Xamarin sample? It seems like several people tried to reproduce this issue but no luck.
We have not received the requested information. Seems the issue is solved so I'm closing this bug.
