I noticed something similar with levels, with 2.8. At least on my computer (opensuse, 2.8 compiled from source) there are three places where "gegl" can be activated in 2.8: "View, Use Gegl", "Colors, Use Gegl", and also "Tools, Gegl Operation". If I use levels to raise the black point of an image (use the lower left slider rather than the upper right slider) from 0 to 25 (ten percent of 255), the shadows should be brighter than they used to be, the midtones affected less, and the highlights hardly at all. Levels with nothing checked or with "View, Use Gegl" checked (and "Colors, Use Gegl" not checked) acts as expected. "Tools, Gegl Operation, levels" using 0.10 (ten percent of 1 rather than ten percent of 255) also acts as expected, producing the same effect as above. But Levels with "Colors, Use Gegl" checked affects the midtones more than the shadows. The difference is noticeable with an sRGB image, drastic with a linear gamma image.
