I guess maybe mine is just too old from before they got this sorted.

From what I remember, mine always fully turns black then clears before rendering. Even big areas of the page that are white both before and after, there was always a full screen black flash. I wouldn't be at all bothered if it was just the areas with text that went fully black before clearing, but it's very jarring full screen.

I think installing KOReader would let you configure it https://github.com/koreader/koreader/wiki/Installation-on-Ko...

That said I have a 2012 Kobo Mini with the option in stock firmware (and an undocumented "only refresh when I choose to" setting too). Maybe there's a firmware update for yours that would add it?

I dug one of mine out of the cupboard and just checked. There's an option for refresh after every: with options from 1 page to 6 pages. I guess better than I remembered, but that's still not what I was after.

What I really want is for the framebuffer to remember past pixels, so that the blacking out is restricted to only areas where there previously were pixel. I don't really mind noise on where the text was while the page is replaced, it the big areas flashing black needlessly that's distracting.

I might try out this firmware over the holidays though. If I get back into using the kobo as an e-reader, maybe I'll look at the issue myself now that it's open source, if it's not been addressed by someone already.

In case it's unclear, KOReader is an application you can run - not replacement firmware.

For the stock reader I believe this was the option I changed to disable automatic refresh entirely : https://old.reddit.com/r/kobo/comments/pbqey3/page_refresh_i...

		Thanks, I hadn't realised that. It's so long since I properly used the Kobo, I didn't recognise any of the names.

I know this is an option since at least 2014, which is when I got mine x) I guess if yours is even older, you might need a software update?
