I'm pretty sure OBS flat out just doesn't work on Mesa right now.

It's a bug with mesa drivers when using the separate shader extensions. I didn't know about it when I was writig it. I can change it to the linked-style shaders, but it'll require rewriting the entire opengl shader source, which will be a serious pain, so I can't do it very soon.
