    I see a similar crash (ShouldUpdateTransformBefore) but also have no ScrollRect. I do have RectTransforms with no width or height, but are scaled to 1. I don't have an iOS device with 10.3 so I am only seeing this from performance reports and users.

    Also had this issue, also fixed it by downgrading to 2017.2. Issue was present at least on iPad Air 1, iPhone X, and iPhone 6+.

    Also have the same issue. I don't have any scroll rect but I load my UI using additive load. Could this be a threading issue. My repro rate is 50%.
