A bit of a guess from OP's screenshot. Typically little diagrams from some colour-to-alpha removed background then pasted in as new layers.
The point about the bug is; taking say, Adjust Brightness and Contrast on an 8 bit image, the preview should not even show that improvement. Try doing that in Gimp 2.8
