As of Wine 1.9.19 the problem still exists. Shader setting "PC2" has graphic errors while "PC3" the game is nearly completely dark.
The game is only rendered correct with these shader settings: "PC0" and "PC1".
Correction: The game has some minor graphic issues with "PC0" and "PC1" (e.g. the clouds in the background) but at least it is playable in these settings.
