Have you tried OpenGL and Vulkan for your PC?
It seems it doesn't occur for D3D9 and D3D11

Hey! @Panderner 👍 ✨

I said ==> "This issue happen only Android". 😆
So, Any backend has no problem on Windows PC.

[Panderner]

Hmm this GE Dump looks right for my Realme C2 and POCO M3 too.

@Panderner

Ooooops!!!
Sorry and Thanks!!
My Phone was turning off on "Hardware Transform"!

Close!!

[hrydgard]

Although that's still a bug! we want both on and off to work the same. I'm reopening, it's probably worth fixing.

[nassau-tk]

Really? 😮 wao...

[Panderner]

If you turn off hardware transform the team symbols disappears.

Hardware transform on:

Hardware transform off:

[Panderner]

@nassau-tk have you tried to turn off hardware transform for your PC?

[nassau-tk]

@Panderner

Yes, I did it.
Result is same yours.

If I disable light 0, it works, so it's definitely related to that. Software rendering is fine, only software transform effected. Disabling alpha blend/test makes it fully black, so it's turning to zero.

The issue here is that normal * world ends up as a zero vector, and normalize(vec3(0)) ends up as NaN. It seems like glsl is handling this better, but I could imagine different drivers / implementations handling differently.

It seems clear from this case that the PSP considers normalize(vec3(0)) to equal vec3(0, 0, 1) or similar, and we've seen this before elsewhere.
