--- Comment #11 from Ashley Gullen <ashley at scirra.com> ---
I took a closer look at our feature detection code, and it looks like we actually already unconditionally disable OffscreenCanvas in Cordova on iOS. So there should not be a risk to iOS apps published with Cordova or WKWebView, at least for our content. Apologies for the confusion.

If you want to proceed with a Safari quirk that detects our engine, I think that window.c3_runtimeInterface is actually created after we run feature detection. Our engine will set window.C3_IsSupported to true prior to running feature detection for OffscreenCanvas, so that may be a better signal.
