Vertical lines issue on Kindle Paperwhite 3 after installing KOReader

Hi everyone,
I’m having an issue with KOReader on my Kindle Paperwhite 3. After installing the app, vertical lines appear on the screen, as if they were part of the book cover. This happens regardless of the file format (PDF, ePub, Mobi). The lines show up in various spots and make it difficult to read. I have to manually adjust the margins—either increasing or decreasing them—to avoid the lines, which is quite annoying.I’ve attached some pictures to show what the problem looks like. Has anyone else experienced this issue or knows a solution?
Thanks in advance for any advice!

Looks like "Perception expander" plugin.
Look at the upper menu - 2nd tab - Speed reading module.

Wow, thank you.
That was exactly what I needed. And I thought I had already clicked through everything...
