It would be nice if you could have a view where all "unchanged" pixels are replaced with bright green or red in a frame. This would spotlight any pixel data that is being stored as a "change" that shouldn't be. Then you could paint over these pixels with the same green or red color. Effectively deleting the "change" in the current frame compared to the prior frame.

An example of this being done can be seen in GIF Construction Set Professional. Although the workflow is horrendous, as the application was originally designed for Windows 95, and doesn't have a great UX. It allows editing of a frame by opening it in MS Paint. Which works, but the app won't update until you close MS Paint. Paint doesn't retain your settings, so if you have a lot of frames to clean up, you'll be manually selecting the eye dropper to set the correct green, then changing the fill/stroke values of the rectangle tool at the start of every frame edit.

In the above frame the only change was from where the mouse was in the previous frame to where it is in this frame. The rest of the noise is MPEG artifacts (cleaning up someone else's screen recording that was saved as an MP4, converted to GIF, MP4 was deleted, and the GIF sent to me). So far gotten it from 43MB down to under 2MB. Chipping away.
