Comics always have ghosting

I have been reading a webcomic on my Kobo Clara Colour via KOReader recently and I noticed that there is almost always ghosting when I tap to scroll down the page.

I have set tapping the bottom left corner to do a manual screen refresh, but I was wondering if there is a way to make it always refresh when I tap to scroll.

Under eink settings I have set "every page" and "always flash on pages with images, but I still get ghosting.

Because it's a webcomic the "pages" are very tall images which require multiple "page turns" to view the whole image.

Is there any way to get KOReader to do a full screen flash every time I tap to scroll?
