Hello!
How to reproduce:
Create unity project with Lunar implemented.
Create canvas with render mode Screen space - overlay.
Create any image under canvas.
Create default event System.
Build for iOS and deploy on device. iOS 10.3.2 and 10.1.1, Unity 5.5.3f1 or 5.5.6p2 or 5.5.1p3.
In runtime place one finger on image and start tapping by second. There will be error:
Stale touch detected!
(Filename: /Users/builduser/buildslave/unity/build/PlatformDependent/iPhonePlayer/iPhoneInputImpl.mm Line: 396)

It is not reproducable without Lunar or with disabled Lunar.

Hi @ngrigoryev! Thanks for reporting, I'll take a look at it.

Hi! Have you reproduced it?
If right solution is hard to achieve, is it possible to customize messages to be warned/not warned about in console pop-up, so we can disable only this message for debug playtest stage? At this stage this pop-up is important to catch exception cases.

Hi, @ngrigoryev! I'll look at it later today. Sorry it's taking long.

It seems like there's an issue with CADisplayLink + CocoaTouch UI in Unity. Needs further investigation. For now, here's a patch which make the plugin ignore "stale touch" warnings.
