STR: 1. play Sanctuary-20131107-with-idbfs until you reach the kill limit (25 kills) 2. when the camera moves above the character, just click on the screen couple of times AR: Unresponsive script error appeared. Black screen over the game area. In browser console: "Error: WebGL: A texture is going to be rendered as if it were black, as per the OpenGL ES 2.0.24 spec section 3.8.2, because it is a 2D texture, with a minification filter requiring a mipmap, and is not mipmap complete (as defined in section 3.7.10)." Reproducible on FF 25-28

Again, doesn't sound like a JS bug (JS probably shouldn't be the default component when filing these unless there is a crash in what looks like jit code or the JS engine or there is some aberrant behavior that is fixed by toggling javascript.options.asmjs or javascript.options.ion.content). Based on the warning, this might be WebGL or it might just be in the the app itself. Tentatively moving to graphics, where people would understand this error.

Sanctuary at that point tries to switch levels, which aren't in the emscripten package. It then just dies and infinite-loops. This isn't a bug on our end, it's a bug/issue in the actual C++ code.
