When the outer doors of the airlocks are open, the shadows inside the building are drawn on top of everything (except the HUD). Disabling shadows in the advanced settings makes them disappear. While being indoors, everything is rendered correctly AFAICT.
With r300c every shadow was drawn on top of everything, but those covered the HUD as well. This might be a similar problem.
Is this with HyperZ enabled?
It's independent of HyperZ.
With current Mesa (rev a87afba50529c6ae6762a3da68d4f31bc431e064) this problem is gone.
