Strange indeed. No, there's nothing currently known, but there may be a bug.
I don't have a Linux machine to test on so I can't verify this, but I think the first thing to do is make certain it's not a path issue or other similar problem. Did you use the "Gather Project" function to package the files and transfer to your Linux machine, or are you accessing the files over the network? If you haven't tried to "gather" the project, I suggest that as a first step in troubleshooting.
If that still doesn't work, see if the result is the same as what you'd get when turning off leaf textures on the Windows version. It does look as if some textures are there, but just incorrectly mapped. So again it may indeed be a bug of some kind, though it seems like an odd one.
Ultimately we may need you to share the scene and its assets for internal testing.
