PIXI.autoDetectRenderer TypeError: gl.getInternalformatParameter is not a function


Recommended Posts

When trying to run PIXI.autoDetectRenderer in Safari 14.1 we get the following error

    [Error] Unhandled Promise Rejection: TypeError: gl.getInternalformatParameter is not a function. (In 'gl.getInternalformatParameter(gl.RENDERBUFFER, gl.RGBA8, gl.SAMPLES)', 'gl.getInternalformatParameter' is undefined)
        (anonymous function) (main.c39d6dcf.js:27763)

       (anonymous function)
        (anonymous function)) (main.c39d6dcf.js:56314:1641)

Here is the code we used

        this.renderer = PIXI.autoDetectRenderer(
            {width: App.WIDTH, 
             height: App.HEIGHT, 
             backgroundColor: 0x0b3a21, 
             view:document.getElementsByTagName("canvas")[0] as HTMLCanvasElement | undefined}

This used to work fine but broke with the latest safari update. How can we fix this?


We used pixi 5.3.3

Safari doesn't offer complete support to webgl2 . At least looks like that function is missing: https://developer.mozilla.org/en-US/docs/Web/API/WebGL2RenderingContext/getInternalformatParameter

You could try forcing webgl1 into use when on Safari (settings.PREFER_ENV). Do you have webgl2 enabled on experimental features? Or could it be that Safari finally has added support for webgl2.
