No Text on PS4: WebGLTexture, createImageBitmap, and ImageData not defined

Another one that was not polyfilled was createObjectURL. This is failing on my Tizen 2.4 device

For createObjectURL, it looks like it wasn't because of missing createObjectURL, but it is actually erroring with a Type Error when executing. It seems the mimetype passed to the function is causing the error. This was fixed for me by setting the type on the blob instead:

const blob = new Blob([code.replace('"use strict";', '')], { type: 'application/javascript; charset=utf-8' });
const blobURL = (window.URL ? URL : webkitURL).createObjectURL(blob);

I'm closing this issue for now, please reopen if still relevant.

I believe the change to _isNativeTexture would still be good to have, we can survive without the polyfills though.

Hey @markus101,

It's possible that webOS 2 was not taken into consideration back when Lightning was tested on variety of platforms in its earlier stages. Currently, we are not pursuing this target, however if you wish to contribute (looks like the solution is already there), we could consider adding the change to mainstream (including polyfills).

Best regards

This issue was originally regarding PS4, which didn't have issues rendering text and even with the polyfills above webOS 2 is unable to render text. I'm not sure this issue is related to #100.

Hi @markus101 ,

I see, since you commented on this issue I thought you've found your answer here. So, if I understood you correctly, the change and polyfills would fix problems on PS4 but webOS 2 is still open, correct?

Best regards

[markus101]

Correct, webOS 2 still has issues. I commented here because as far as I can tell the _isNativeTexture wasn't implemented and will still affect PS4.

@markus101 , thanks for clarification. We are not running any tests on PS4 neither, so if you wish to contribute a fix and can confirm it works on PS4 platform, we can include it in upstream. I'll reopen the webOS 2 issue then.

Best regards
