@MeiGuddet: I'm confused.
When you turn a page, what should happen is that the page turns, (obviously ^^), at which point the MiniClock display has completely disappeared, and only the new page's content is visible (barring eInk ghosting, which may be plentiful on an Aura, making the issue more confusing). Then, a few dozen/hundred milliseconds *after* the new page has been shown, the MiniClock display redraws.
Now, the Aura was a special snowflake as far as how the eInk tech is handled, so the way the screen deals with that in practice may be extra wonky. But I wouldn't mind more details, and an actual picture if at all possible.
I don't think it'll change anything, but you can also try the version from
#311 on the off-chance it's a weird bug I already fixed in FBInk.
