bevy_rapier shaders fail on AMD Radeon Pro Vega 20

[brandon-reinhart]

Post here to cross link the issue from bevy_rapier : dimforge/bevy_rapier#226

The error says to report it here. I don't know if the problem is in the shader or the compilation of the shader.

Device: AMD Radeon Pro Vega 20
Backend: Metal

If you add RapierDebugRenderPlugin::default() to this device and backend the shaders fail to compile. This may actually be a naga bug in translating the shaders.

Have the same situation on mac with no discreet card. So the issue seems to be unrelated to a specific video card and likely more broad.

AFAICT it is happening more broadly for macOS: dimforge/bevy_rapier#230

I'm using an M1 chip and have the same error (info in issue above).

This was fixed downstream in dimforge/bevy_rapier#238

We are most likely missing this piece of validation.
