I get the following error repeated 200+ times on game start with v2.19.1: `WebGL: INVALID_OPERATION: drawElements: no buffer is bound to enabled attribute` Traced down to `PIXI.WebGLSpriteBatch.renderBatch @ phaser.js:20295` The game remains black (audio and inputs still seem to be working). I don't have any issues at all with the previous v2.19.0 version. Any ideas?
