Linux: Shading bug


I have some graphic troubles with your game. The main menu and the formicarium view looks good but when I play a level (Formica fusca 1.1 and 1.2) the shading looks weird. The effect is different everytime when I quit and restart the level. Sometimes colored, sometimes just white.

Level 1.1 and 1.2

Formicarium view with little graphic problem:

I tried several graphic settings but it doesn't change.

Thank you. Our Linux testing group is tiny so we don't have much data to go on. Will pass this on to the guys.
