In version 3.03 auto section control works. In versions later than that it does not work.
I have found that the ReadPixels function in OpenGL.Designer.cs line 637 doesn’t return any green pixels. AOG doesn’t find the green pixels on the previously applied area so it doesn’t turn off the sections.
I should remove that version
It’s the newer versions that don’t work.
It was a video driver issue. It works now.
