Lower visual quality for sprites when switching from bevy 0.9.0 to 0.9.1

[GuillaumeGomez]

Hi,

I'm not sure if it's a bug so I opened a discussion instead. Switching to bevy 0.9.1 greatly reduced the visual quality of the sprintes and I now have this rendering:

To be compared with 0.9.0 (for the background, I can change it with ClearColor I suppose):

If anyone has an idea what might have changed, it'd be very helpful. Here is the repository: github.com/GuillaumeGomez/rust-toy-game.

Are you talking about the light gray pixels around the sprites? It looks like they are part of the texture and just happen to match the old ClearColor. Therefore they were not visible on the previous background but are on the darker background.

Then it might be a blending issue. The gray pixels might have an alpha value close to but not exacly zero and blending seems to be disabled. Possibly related to: #6315

Interesting. I didn't know that depending on what settings you have in your image, it might impact the rendering like this. It seems to be a bug indeed. But I'm not sure why it worked before though...

For 3D, the StandardMaterial type has a field alpha_mode to specify how the alpha value is used (Blending or Mask). But I don't see a way to configure this for ColorMaterial in the docs. I might be missing something.

I just realized that I was using the Intel Integrated GPU and not my NVIDIA one so I just updated the driver and switched back to using the NVIDIA driver and now it creates a window but seems to be stuck in an infinite loop. Going to open an issue.
