Would be nice to read the full thesis. This is a pretty naive question, but I wonder if retaining the current frame (just as pixels) and only redrawing when there are actual changes is a good middle ground? Is this something already being done in immediate mode GUI libraries?

Determining where there are changes would likely take up the bulk of the work to actually redraw in this scenario I would think, since you'd (to some extent or another) have to draw the new state to be able to compare it to the current state.
