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?
