The way I implemented it was by updating the "official" back frame

and went on from there.

Is this where the need for “triple buffering” comes from -- the fact that
you need to copy the entire contents of one buffer to another?

The way I understood to do flicker-free drawing was with just two buffers
-- “double buffering”. And rather than swap the buffer contents, you just
swapped the pointers to them.
