Some lights not working on Linux with AMD APU's (and potentially GPU's as well)

[ferafiks]

Release Type: Official Release

Version: 4.3.0.2507

Platform(s): Linux (arch & steamOS)

Describe the bug
Spot lights don't work on Linux with AMD APU's, which includes the steam deck on OpenGL. I have installed all dependencies and was able to launch multiple projects with no problem, except for spot lights not lighting anything.

However, on Windows on the same machine, everything worked fine on all Graphics API's. Also, on another machine running Linux with an Nvidia GPU, everything also worked fine.

I have only tested spot and directional lights, so I'm not sure if this happens with other types as well.

To Reproduce
Steps to reproduce the behavior:

1. Find a machine with integrated AMD graphics running Linux and install required dependencies.
2. Create a simple Stride game that uses spot lights.
3. Run the game on the Linux machine and compare results to Windows.

Expected behavior
The game looks the same on both platforms.

my computer is gasslighting me and lights started magically working today. I'm still gonna try it out on steam deck and test other graphics APIs

So it turns out that this is only a problem with OpenGL on Linux. I still would like to test this theory on my steam deck, but technology seems to hate me today and my external ssd stopped working again
