Safari 15 blank canvas

Question

Safari 15 blank canvas

TyLindberg opened this issue 3 years ago · 6 comments

With the release of desktop Safari 15, the Jeeliz demos seem to be breaking. The browser will prompt for camera access, but then the experience will be a black or blank screen.

This bug seems to affect both the 3D and 2D demos, and as far as I can tell no bugs are being logged to the console.

All my testing was done on MacOS 11.6, Safari 15.

Canvas2D Draw Demo:

Hi @TyLindberg

Thank you for your report, it seems really strange. I will try to test it on a mac too.
Can you provide:

Does https://jeeliz.com/demos/faceFilter/demos/threejs/cube2cv/ work? Can I have the logs from the web console ?
The logs of https://jeeliz.com/demos/WebGLCoreLogger/index.html
Can you test these 2 Jeeliz FaceFilter links:
1. https://jeeliz.com/demos/tests/updated_FF/
2. https://jeeliz.com/demos/tests/updated_FF_noAsyncReadpixels/

Thanx

Hey Xavier! There is a bug on iOS 15.1 betas (both 1 and 2) that breaks camera access. According to bugzilla, a fix is due in the next beta. Details here: https://bugs.webkit.org/show_bug.cgi?id=230617

Thanx @andrewdeutsch
I can reproduce the bug on Safari 15.0 and Mac OSX Catalina (10.15).
I am updating MacOSX and I will test again...

Ok so for an unknow reason, it is not possible to refresh a WebGL texture instance from a video.
It does not trigger any error or warning, the WebGL texture just stays black...
Both with WebGL1 and WebGL2.
The camera video is fine thought.
I tried to change some texture parameters (set texture filtering to gl.NEAREST instead of gl.LINEAR, change pixel packing, ...) but nothing to do.
I hope Apple guys will fix it soon...

Looks like this issue is resolved in Safari 15.1
