Hello is anyone else experiencing this error on iOS 13:

Here's the full message:

Need more info. Pixijs version?

[Aaron McGuire]

"pixi.js": "5.1.2",

"@pixi/filter-adjustment": "^3.0.3",

"@pixi/filter-advanced-bloom": "3.0.3",

"@pixi/filter-glow": "3.0.3",

[ivan.popelyshev]

Lets check newer, try 5.1.5 please?

Can you also try to switch off filters? I mean dont use "filters = [ stuff]" , that's enough to check.

@ivan.popelyshev I was able to isolate it:
https://www.pixiplayground.com/#/edit/WAL9OjtbQMP6aKxkk~4fw

I found that if the radius is above 76 on ios13 it triggers the error above.

Also happens on this examples page:

https://pixijs.io/examples/#/graphics/advanced.js

[ivan.popelyshev]

The difference is in number of vertices.

We use either Sprite BatchRenderer if its small

or "Graphics.renderDefault" for big number.

That code will use "renderDefault" for all graphics, and you'll have that error always! 

PIXI.GraphicsGeometry.BATCHABLE_SIZE = 1;

Make that number big enough - all your shapes will fit in batcher instead and it'll be ok.

That narrows the code segment but i dont have iOS devices to test. Gonna call rest of the team on this.

I think its possible critical issue, need to reproduce and fix it ASAP.

@Aaron McGuire can you please try put that line before renderer/application creation? 

PIXI.settings.PREFER_ENV = PIXI.ENV.WEBGL
