A small mod can be applied to improve the Divide overlay *as long as no one objects*. (most like Gimp). Old projects can use a previous AppImage to get the previous results. The mod seems to fix the minor imperfections you can see in the following screenshots using the Overlay plugin. hhttps://cinelerra-gg.org/download/testing/divide_flowers.png (Top first layer order) In both Cinelerra 7 and Current CinGG, look at imperfection on upper right hand corner about 1/3 of the way down where there are 2 small red rectangles. And there are small dark blue squares scattered around in the light blue areas. These look wrong to me. https://cinelerra-gg.org/download/testing/divide_waterfall.png (Bottom first layer order) Entire left hand side just looks ugly for both Cinelerra 7 and current CinGG. I do not think anyone would want this output. https://cinelerra-gg.org/download/testing/divide_squares.png (Top first layer order) This test is interesting because all 3 look the same with no obvious imperfections.
