```
The detection of OffscreenCanvas in three.js is
https://cdn.8thwall.com/web/aframe/node_modules/super-three/build/three.js
```
var useOffscreenCanvas = false;
try {
useOffscreenCanvas = typeof OffscreenCanvas !== 'undefined' && new OffscreenCanvas(1, 1).getContext('2d') !== null;
} catch (err) {
// Ignore any errors
}
```
it will be set to true.
Another detection in
https://cdn.8thwall.com/xr-simd-21.3.8.997.js
```
oA = function() {
return window.OffscreenCanvas ? new OffscreenCanvas(0, 0) : i("compute")
},
```
so far so good but this is used in
```
var I = !1,
g = aQ(aQ({}, iA), D.glContextConfig || {});
D.webgl2 && (I = (Q = C.getContext("webgl2", g)) && n(Q)),
Q || (Q = C.getContext("webgl", g)),
Q || (I = (Q = C.getContext("webgl2", g)) && n(Q)),
// Here B is the OffscreenCanvas
B || (B = oA()),
(E = B.getContext(I ? "webgl2" : "webgl", g)) && !E.isContextLost() || (B = oA(), E = B.getContext(I ? "webgl2" :
"webgl", g)),
t("[XR] Using WebGL", I ? "2" : "1"),
UC(Q, D.verbose, !0, I),
//calling UC with E null
UC(E, D.verbose, !0, I);
var i = E.getContextAttributes();
```
B -> OffscreenCanvas
I -> false
So we got B.getContext("webgl") or B.getContext("webgl2") returning null
so E is null.
Then E is passed to UC
```
function UC(A) {
var I,
g,
C,
Q,
B = arguments.length > 1 && void 0 !== arguments[1] && arguments[1],
E = arguments.length > 3 && void 0 !== arguments[3] && arguments[3],
D = (I = {}, c()(I, A.TEXTURE_2D, A.TEXTURE_BINDING_2D), c()(I, A.TEXTURE_CUBE_MAP, A.TEXTURE_BINDING_CUBE_MAP), I);
E && Object.assign(D, (Q = {}, c()(Q, A.TEXTURE_3D, A.TEXTURE_BINDING_3D), c()(Q, A.TEXTURE_2D_ARRAY, A.TEXTURE_BINDING_2D_ARRAY), Q));
```
So it will throw here as soon it is requesting things like
A.TEXTURE_2D which would be basically null.TEXTURE_2D.
Currently in Safari 16.4
> offscreen = new OffscreenCanvas(1,1)
< OffscreenCanvas {width: 1, height: 1, getContext: function, transferToImageBitmap: function, convertToBlob: function, …}
> offscreen.getContext("webgl")
< null
> offscreen.getContext("webgl2")
null
