Help needed, remove lines in ebook
I'm not sure if this is the right place, but correct me if I'm wrong.
In most of my ebooks I have strange lines, they don't disturb me that much,
but the problem is, that it takes a really long time before a page is loaded.
I have tried a couple of settings, and I want to completely remove them.
The images that I have added show the lines, I tried a lot of settings and it doesn't help anything.
