fbcon doesn't clear on SPRIXEL_MOVE #2057

Open dankamongmen opened 3 years ago

I'm pretty sure the framebuffer console backend isn't handling SPRIXEL_MOVE properly, as we have lingering aftereffects in both intro and box, the two demos which cause a SPRIXEL_MOVE. This has been the case as long as I can remember.

This might be related to #2106, or might not.

2147 is likely relevant.

so far as i can tell, the only thing we can do for this is scrub everything, the same way we do sixel. we need damage all the cells under our old instance. there seems to be no way to undo fbcon graphics otherwise.
