since alpha 47 all textures are y-flipped in WebGPU (https://playground.babylonjs.com/#YDO1F#18).
also, when you switch back from webgl to webgpu in the playground, Chrome Canary just closes.
There is also the very strange thing that canvas PointerEvents offsetY is flipped as well when WebGPU is enabled. This was already there, and doesn’t seem to be a Babylon issue, but I’m mentioning it because it might be related, who knows.
