It looks like it tries to keep the caret visible.  There is no flicker if the caret at the end of text.  If you look at how JTextField behaves in a similar situation, there it tries to keep the end of text visible.
So perhaps if we change the logic to keep the end of text, instead of the caret, visible, the flicker might go away.
(Just a suggestion)
