another pdf problem not encountered before: I OCR'd the pdf myself with Adobe Acrobat DC2019 (60 MB, with pictures). The pages are too wide to read them even in landscape, so I switched to text reflow. Every 20 page or so a paragraph's font turns minuscule, and sometimes even lines are mixed up. Could this be due to low RAM or processor of my Kobo? I'm on KoReader 2019.12 - screenshots
