Confirm iOS 7.1 alert rendering issue about sdcalertview

[sberrevoets]

I believe I know what you're talking about, but this also happens on iOS 7.0, and I don't think it's limited to alerts. An alert is the best way to demonstrate it, but if you look very carefully (maybe even slow it down) at the default push in a navigation controller, you can see it happening in the navigation bar too. A toolbar is probably the same.

I believe this is a trait of the backdrop view that finds the middle ground between performance and live "blurring". We have established an alert doesn't have a blurred background, but UIBackdropView has a method to turn that on or off. I imagine that the backdrop doesn't do "it's thing" (whatever that may be) until all animations that involve it are finished.

So yes, you can call this a UI glitch, but it was probably done on purpose for performance reasons. If you want to file, go ahead and I'll dupe it, but I wouldn't expect too much from it unless they figure(d) out a way to make live blurring more performant.

I'm going to close this issue as it isn't really a bug in SDCAlertView. I'm interested in discussing it further though.
