There is a problem with the draw ordering leading to a transparency bug. It seems, that the trees are done by only two triangles, intersecting each other. Due to the intersecting none of the two possible orderings are correct. At least one of the two triangles need to be separated into two triangle (along th intersection line). > At some point I'll need to add a setting to the preferences.xml file too, but > first we need to decide whether the trees should be on by default (like the > random objects) or not. > > If it don't affect slower PCs with older graphics hardware I will suggest "on" as default. But if it causes frame rate drop on older hardware while nothing is displayed, off should be the default.
