I think it's the transparency in the texture that is the problem. On a related note, the visual realism of Flightgear can be increased if Bi-directional Reflectance Distribution Function (BRDF) can be incoporated when applying textures to vegetation area, especially for area that are at considerable distance from the camera. Basically, this is to simulate the reflectance and transmittance of a canopy when view at different angle, and could give similar results to using million of tree models, without actually using million of tree models.
