> this.aTextureIndex = 3; Why 3?

Thanks. What's the error message? Did it ever work in a previous Phaser version?

Also what exactly is a "Collection of images" tileset?

I guess we don't support a "Collection of images" type. I can add a warning message.

I'm not sure how much work it would be to add it. Hopefully someone with some knowledge can pick it up.

So removing `txt2.anchor.setTo(0, 1)` eliminates the problem?

It looks like an anchor change triggers `BitmapText#updateText`.

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

Please view [filters/bacteria](https://samme.github.io/phaser-examples-mirror/filters/bacteria.html) 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.

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