Trying to read Manga Pokemon Adventures, but it's really bad

I'm trying to read the manga, but the browsing is very bad, it always cuts some parts of the page and the experience is not good. Do you guys know how to make it work better?

I have the files here if you guys want to test on your devices, I have only the pdf

My device is a kindle paperwhite 10th generation, and I'm running koreader with the default settings
