Can confirm. I own a Poke 5P and the ghosting is really more obvious until you've fiddled with the settings enough - and I do mean fiddle here. Might take a while.

Other than that I'm a real fan: latest update delivered dark mode (black background, white text) and like I said above: no ads, no Amazon-DRM, all formats, cloud storage (if you want to), TTS, annotations that are really comfortable to handle, bluetooth.
