Seeing these crashes from real users in iOS7. Can not repro on our devices. Can anyone advise me? Are these crashes in my own C# code? Are these crashes during rendering?

Seeing pretty much the same crash here. In our case, we have a UIWindow (which hides Unity) where we present scrollable UITableViews. When I scroll down too much and too fast, I get this crash a lot (so I can reproduce pretty reliably). That’s all I know right now, though - still researching.

Well, someone has already posted a workaround! Works in our case: http://forum.unity3d.com/threads/203506-Workaround-ios7-DisplayLink-Scrolling-results-in-crash

Hey Vladimir, can you post that URL without it truncating? Or send me a message? markj@markj.net
Thanks.
