A common pattern when rendering to WebGL is creating an ImageBitmap, rendering into it, and then uploading the result into a WebGL texture. This is typically done for text rendering, for example. When the created ImageBitmap is big enough, it's created as accelerated, which means that it's backed by a gl texture instead of a normal buffer. In this case, trying to render the content of that ImageBitmap won't work as expected. It may cause a crash or fail to actually render properly. The problem can be avoided by not accelerating ImageBitmaps, which is why I know that the problem is related to the accelerated ones. It can be reproduced with https://strike.lightningjs.io/es6/#home where the rendering will be wrong.
