The flashing is to prevent ghosting in the display (and I'm sure it's the controller that does it, not the actual display), so it'll stay until eink creates better displays (although it might be optimized so that not the whole screen flashes, just the changing parts).
However, one thing that advanced low level functions should
be able to support is to provide non-flashing, local drawing when ghosting isn't so important. E.g., who cares if the menus are a bit ghosted if they are 3 times faster that way? The same should go for other small, momentary stuff, such as pointers, scribblings, highlights, etc. That way you could still have it be somewhat responsive even if the anti-ghosted fullscreen refreshes are awfully slow.
