Symptoms

SpaceEngine crashes from the splash screen very early in the loading process if the system has an AMD GPU and Mesa is version 20.3.1. Downgrading to Mesa 20.2.6 allows the game to run normally.

This is also happening to an Arch Linux user with newer hardware, and they were able to reproduce the downgrade workaround: https://steamcommunity.com/app/314650/discussions/1/5242718027649464482/

Reproduction

1. Switch the system Mesa version to 20.2.x
2. Start Steam, launch SpaceEngine, watch it run normally
3. Switch to Mesa 20.3.x
4. Restart Steam, launch SpaceEngine, watch it crash
