Comment 12 for bug 1070275

Definately Vertex Buffer Object that solved it. I've still got Framebuffer and Buffer swapping still checked.

Lighting []
Sync to VBlank [X]
Texture Compression []
Framebuffer Object [X]
Vertex Buffer Object []
Always use buffer swapping [X]

Is my current setup, if I check the VBO option the flickers return.
