Description Martin Robinson 2012-05-29 17:31:12 PDT
When interacting with http://www.ibiblio.org/e-notes/webgl/deflate/ship.html with TextureMapperGL enabled, the canvas content does not update after the first render. It seems that Nvidia cards require manually rebinding to the multisampling FBO after multisample resolution. This is likely because the texture cannot be active on two framebuffers at once. This does not seem to be an issue for my Intel driver.
