@rdn@Teasday I'm on last Chrome, last Win10 on a 14" 1080p laptop (100%dpi tho). The reader is set for "fit width". The last page here dose something STRANGE, it's like... vibrating or something. I think it's a bug. Probably can be replicated.
Yeah, sorry. Known bug with the reader, it happens on fit to width when the image height is almost exactly the same as the container height on your screen, causing the scrollbar to appear and disappear repeatedly. It's not that the image itself is bugged or anything.
