Looks like a glitch with the scroll graphic. There have been a couple reports of glitches happening with dropped items (someone posted a screenshot of a giant club that dropped in the alpha, but after picking it up it was normal size when dropped again).
If you wouldn't mind, please email supportdos@larian.com, with a brief description of the problem, maybe a link to this topic for the screenshots, and the report.zip file generated by the
D:OS support tool (for the PC version). To reduce the file size, you can delete all but that save from the zip. Maybe that will help Larian track down the cause of the glitch.
