    Intel HD Bug - Set RGB different from Get RGB (OpenGL)

    jh

      hi,

       

      i found a strange bug. when i set a value in the color buffer, let's say RGB = 150/140/130 and read

      the same pixel i get a little bit different values, such as RGB = 149/141/130.

      i use OpenGL functions to do that.

      i have this problem on a i5/HD 3000.

       

      since i use these color values to identify objects (ID -> RGB, RGB -> ID) i get wrong objects

      as a result.

       

      anyone an idea how to solve that?

       

      best regards,

      jh
