I recently released my contest entry game, and found that it did not work at all on integrated graphics cards, like the X1300 on a lot of previous generation macbooks. It turns out that there is a call "GL13.glActiveTexture(GL13.GL_TEXTURE0);" inside Thingle that is not supported by the Java OpenGL bindings.
The message I got was:

And I fixed it by simply commenting out the line 241 in org.newdawn.slick.thingle.internal.lwjgl.LWJGLContext.java. I know that's probably not a great solution, as it doesn't really reset the active texture, but I guess I never used that call. This is kind of out of my area of expertise, but perhaps the call could be skipped if it's not supported?
