Should this be happening to the screen when I start a new chapter? (Aura H20)

lealla · 10-15-2015, 02:13 AM

Hey all,

Got my new Aura H20 all set up and starting reading (loaded kepubs from calibre).

I noticed that on the page turn from the last page of one chapter, to the first page of the next one, the screen refreshes oddly.

It flashes black on and off about 3, 4 times, between the text and a black screen. The first time, I thought it was having an error, because it looked like a little electrical spasm.

I've noticed if I flip back to the last page and then back again, it doesn't repeat this flickering, so it must be something to do with time and refreshing.

I found it a little distracting in the reading experience - especially if you have a book with short chapters as it happens frequently.

Any tips? Is this normal?

I'm wondering if it's something to do with the fact that the layout of a chapter often means there is some blank space at the top of the screen (the text starts halfway down the page).

It is a bug that appeared in firmware 3.18.0, hopefully Kobo will fix it in the next firmware release.

You might be able to stop it happening by closing the book and re-opening it again, but the next time you put the device to sleep, use the dictionary, or do a number of other things from within the book it will start again.

It is interesting to note though, Not all users of firmware 3.18.0 have this bug.
I don't have this bug at all and have never seen it manifest across any of the households readers.

Not sure why that is, but there you go.

I think it also depends on the formatting of the first page of the chapter. The first book I saw it with, most chapters was a less than a single screen with the font and size I use. The first chapter that showed this, had one line on the second page. Resizing the font so it all was on one page removed the flashing. The next kepub I read had no extra formatting for the chapter start (the chapter heading was a paragraph with no extra formatting) and no strange flashing. The next one had flashing when there was a sub-heading on the page.

My guess is that something about the first page is "confusing" the layout engine and causing a redraw and the extra flashing is caused by that. I don't know if that is correct, but the extra flashing only seemed to occur on chapter starts pages that had some extra formatting.

I've got the bug and read only Calibre generated kepubs. It doesn't really bother me.
