It appeared to me that everything that was going to be rendered passed
through the effects somehow (screen and windows). Obviously I missed
something :). I will make a much more careful analysis of the code
before I start working on anything.

The idea was that the effect would just call some glBindTexture(3d
color correction texture) depending on the monitor corresponding to
the area to be painted, no changes to the shaders. Anyway, I will
search for other solutions, that do not involve an effect.
