Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3023.0 Safari/537.36 Steps to reproduce the problem: Note: enable 'experimental canvas features' in chrome://flags 1. Visit https://www.scirra.com/labs/bugs/offscreencanvas-oom/ 2. Click 'Crash' What is the expected behavior? The button simply calls transferToImageBitmap() on a WebGL 2 context from an OffscreenCanvas. What went wrong? Chrome throws an 'Out of memory' exception. It works in Firefox Nightly. It also works in Chrome with a WebGL 1 context. Did this work before? N/A Does this work in other browsers? Yes Chrome version: 58.0.3023.0 Channel: canary OS Version: 10.0 Flash Version: Shockwave Flash 25.0 r0
