--- Comment #31 from Béla Gyebrószki gyebro69@gmail.com --- The patch works and fixes the problem for me. The trickery here with the patch is that the 'Direct3D' registry key must exists. As you may already know that registry key is not present in a clean wineprefix and the problem with the white squares are present even though the patch is applied. After creating Direct3D under HKCU/Software/Wine, the patch works indeed and textures are rendered correctly.
