[Webkit-unassigned] [Bug 216106] [iOS WK1] Crashes when using ANGLE WebGL from another thread

[bugzilla-daemon at webkit.org]

https://bugs.webkit.org/show_bug.cgi?id=216106

--- Comment #13 from Dean Jackson <dino at apple.com> ---
My understanding is that the remaining steps for a fix are:

- [ANGLE] patch to allow multithreading support for EAGL backend

- [WebKit] release the EGL (which is from ANGLE, not EAGL) context as we release the WebThreadLock, somewhere around MainRunLoopAutoUnlock

- [WebKit] have the WebThread release the EGL context if the main thread wants it. This would likely be just releasing it unconditionally in prepareCanvasForRendering if we're in WK1 and are holding the context.
