Dude! Please don’t cross post.

I can see the problem in instances of one particular tree.If the tree is generated in parts ( i.e Scene graph), it may that the parts are misaligned.

Other vague reason can be , assuming the tree is textured , some problem with the texture.

Hope this helps.

Adjust your alpha func and turn on alpha blending.

Any follow-ups please post to this thread.

This has nothing to do with “OpenGL Shading Language”.
