Problem here is CLI and text editors who use the scroll rastport feature. We want the text to scroll but the background to stay.
Solution would be to make a bitmap buffer where the original window content is stored and then to blit it with a mask based on color 0 onto the screen. Negative part is that the refresh rate wouldn't be to good with sub GHz Amigas. (Not suitable for media apps)
The best solution would be to make a patch that you configure per app to utilize the most optimal solution. What atlest need to be done is to patch RectFill and the Text function. I think the window refresh function using something else than the RectFill to clear the background. (Has to be patched too)
I don't think there can be a general solution for now. It has to be done per application. :-(
