This is something that has happened since I upgraded to 9.10, but haven't got fixed yet.  

I'm playing [Blob And Conquer](https://apps.ubuntu.com/cat/applications/precise/blobandconquer) but it doesn't have the textures it should have:

Even the weapons have no texture (compare the bottom-left corners of the screenshots).

**Why is this happening? What can I do to fix it?**  

I can even modify the code if needed. I guess this has something to do with SDL.
