Hi,
Each gif frame can have a max output of colors, and the program currently uses a method to save color palette space by replacing the unchanged pixels with a dummy color that will be ignored by the program that plays the gif (like, your browser).
You can try to change that dummy color to a different one in the Gif Settings page.
You must select a color that will not be part of your recording, or else you will lose quality.
