TRADE slight degradation of type definition for elimination of flash to BLACK and increase battery life ...

The latest firmware updates have reduced ghosting
(this has -slightly- slowed page turn times)

so... as the ghosting is greatly reduced ...

you might want to consider completely STOPPING the screen flashing to BLACK every 1-6 page turns due to the old refresh scheme,

and

- get faster page turns that are
- easier on eyes &
- increase in battery life too

* kobo mainly uses battery to draw new pages *

it takes more power to refresh a page to black and then display the new page than to just "overwrite" old page with new page]

You do this easy-hack by re-setting the refresh variable to 90
as follows:

[Connect kobo to your computer with hidden files displayed]

Navigate to the file:

Kobo eReader.conf (there's a space in the name)

found at

KOBOeReader/.kobo/Kobo/Kobo eReader.conf

* BACKUP the file 1st *

Copy file:

Kobo eReader.conf and rename it to
Kobo eReader.conf.orig

Then make the change in

Kobo eReader.conf

[at ~ 40 lines from the end of the file]

in the [Reading] section ...
change the value of variable

numPartialUpdatePageTurns

from (1-6) to 90

to give result as follows:

numPartialUpdatePageTurns=90

Save file and Exit

Now while reading, enjoy flash free reading and if you notice ghosting (after very MANY page turns) to clean up the type

MANUALLY REFRESH PAGE by ...

1) touch page bottom then
2) touch page middle

Quick and Easy!

Thanks for that 2bits!

If you set refresh to 90, and go to reading settings, the Page refresh section, the "Refresh the screen every:" drop down menu says "OH THE HUMANITY!"

Sooo funny! Hahaha

That's right.

I'm glad the working folk at Kobo
are able to keep their sense of humour -
they're sure to need it some days

Oh the humanity - indeed

This is neat, I have it set to refresh every 20 pages on my Glo and there is not even the slightest trace of ghosting.

Thanks! I'll give it a shot.
I just discovered a typo in my original post and corrected it (wrong "TrollTech\QTEmbedded-4.6.2-arm", correct "Trolltech\QtEmbedded-4.6.2-arm"). Maybe you could correct the typo in your quotation too, in case somebody takes the code from there. Thank you!

Ah... the joys of case sensitivity.

I was having an issue with pages looping back after say, five or six and then keep doing several times until it lets you continue. I read a post elsewhere (can't remember where now) that getting rid of the page borders fixes this. I found you can leave the border setting at the first step ( almost gone) and it works just as well. No more looping. I do think however that this is an issue that needs to be rectified in the next F/W release.

I have seen that a couple of times. But, it has always been a corrupt book. Fixing the book and putting it on the device again solved the problem.

I read "Kindle the new book method" in Japanese. I've learned two things in this book.

1) Manage our books in our PC and just keep the books, which we reading now, in Kobo (kindle).
2) We should check the progress by percentage not page number. Page number is not consistent in epub in general.

Actually these two things avoid trouble in ebooks too.

I'd love to try this on my Aura, but the "numPartialUpdatePageTurns" is not in my Kobo eReader.conf file. I'm running firmware 2.5.1, on the Aura HD.
Here's what I see under the [Reading] section of Kobo eReader.conf:

[Reading]
libraryShowCovers=true
pageTurningOption=option1
readingAdobeShowPageNumbers=false
readingAlignment=
readingFontFamily=Georgia
readingFontSize=36
readingLeftMargin=4
readingLineHeight=1.4
readingRightMargin=4

Has anyone else had any luck getting this great little trick to work on their Aura running 2.5.1?
