We have a new GEGL plugin that makes a rgb glitch effect by moving the Red Green and Blue channels independently.
A general rule when using this plugin is try to make sure two sliders are equal opposites. In example if Red Horizontal is 9
Blue horizontal should be -9 (negative 9) try to balance all of them out that way as that best makes a stereo glitch effect. There is also a slider that attempts to removing glitching on the borders but it isn't perfect.
Fun Fact if you look at the code you will realize this plugin has a extremely complex GEGL Graph, perhaps one of the most complex graphs I ever wrote.
This plugin internally calls `gegl:inner-glow` that ships with GIMP 3.
