The Disposal Method property of an image frame specifies what to do with the current image being displayed before moving to the next:
The Gif Screen Recorder uses Do Not Dispose because that way it needs not store images fully, but only the parts that are different from the previous image, which keeps the gif file small.
When you Add new images, these are stored fully, with Restore To Previous. That way, the inserted image does not disturb the flow of a recording.
To change the Disposal Method:
To show the Disposal Method column:
