OK, more testing today... As AMD just released new Catalyst drivers, I first uninstalled the current ones and tried the game with FOSS drivers. Grass looks as it should - no flickering. So, not a Wine bug (sorry for that!).
After installing new catalyst drivers, this bug is gone even there.
Upstream then.
