Firefox Mobile error: WebGL warning: vertexAttribPointer: -1 is not a valid index

[Zykino]

• A bug in the API:
  • Phaser version(s): v2.8.4
  • Live example: Memory done following phaserjs.com's tutorial
  • What should happen: Phaser should select CANVAS since it is in auto when I try it under Firefox Mobile 55 (Android 7.1.1)
  • What happens instead: I see the Game view, but nothing happen when I click to pass the title screen. On the console I have the following: Phaser CE v2.8.4 | Pixi.js | WebGL | WebAudio " http://phaser.io "♥♥♥ Error: WebGL warning: vertexAttribPointer: -1 is not a valid index. This value probably comes from a getAttribLocation() call, where this return value -1 means that the passed name didn't correspond to an active attribute in the specified program. ...
• A problem with my own code (maybe)

I think it really is a bug in PIXI.js OR Firefox Mobile but since I know none of them...

Be nice. We do this for free. <3

If Firefox Mobile supports WebGL then Phaser will use it (for AUTO). You can try CANVAS instead and see what happens.

[samme]

Please view filters/bacteria and see if it runs and if you get the WebGL warning in the console.

If you get the warning, please expand the trace and note it.

Animation is working but in the console I got:

If the animation is still running it seems the WebGL error isn't fatal.

[Zykino]

Yep at first I thought it was the error blocking my game from working but in fact not.

Still seeing Error messages in the console (even non blocking ones) is concerning. I don't have those when I activate the "Ask the desktop page" option.

For the sake of checking when going on the page https://get.webgl.org/ I don't have anyting about WebGL. Only this: using requestAnimationFrame tdl-minified.js:28:213

The same error is repeated on 2 different lines: phaser.js:18818:9 inside:

PIXI.WebGLSpriteBatch.prototype.flush = function () {
...
gl.vertexAttribPointer(shader.aTextureIndex, 1, gl.FLOAT, false, stride, 20);

phaser.js:19813:5 inside:

PIXI.WebGLFilterManager.prototype.applyFilterPass = function(filter, filterArea, width, height)
...
gl.vertexAttribPointer(shader.aTextureCoord, 2, gl.FLOAT, false, 0, 0);

Don't think I could help you more on this one. Tell me if I should report it to PIXI or to Firefox.

[samme]

It's likely a Phaser issue but it's hard to debug.

You can try

game.camera.fx.kill();
game.debug.sprite.kill();

to see if it makes any difference.

Same error but the evening (both with and without your code) I only see the error on line 18818: Error: WebGL warning: vertexAttribPointer: -1 is not a validindex. This value probably comes from a getAttribLocation() call, where this return value -1 means that the passed name didn't correspond to an active attribute in the specified program. phaser-test.js:18818:9 32 times

Just to be sure my code look like this:

window.addEventListener("load", function () {
    let game = new Phaser.Game(500, 500);
    game.camera.fx.kill();
    game.debug.sprite.kill();
    [...]
}
