    Strange bug with GL_ARB_occlusion_query



      my video: HD5830 (catalyst 10.*, 11.*)

      GL_ARB_occlusion_query does not work properly: I draws object in invisible area, query returned 84 visibled fragments

      Example: http://www.codesampler.com/source/ogl_occlusion_query_arb.zip

      Sphere is behind plane,  program prints "sphere fragments = 84", must be 0. GeForce returned 0.
