Shader problem on Linux

[infinite_monkey]

I have a problem with Tundra Exploration's sooty shader for the Falcon 9 aka Ghidorah booster, as well as with the textures from Textures Unlimited - they're all pitch black. There were no clues in the logs about the cause of this. Running on Manjaro Linux, GPU is a Radeon RX 470.

After looking around for a while, a found a workaround on Texture Unlimited's GitHub: it works when I set the -force-glcore42 -force-clamped start parameters. However, it seems that this setting causes a bit lower FPS and higher GPU temperatures.

Does anyone know a better solution?
