e-reader text inverted in windows 10
Have just upgraded my windows 7 virtualbox vm to windows 10 (v. 1909).
The issue: The latest 64- and 32-bit versions of Calibre (4.8) both display epub books in the e-reader with text upside-down and left-right flipped (I think). I have attached a snap of what it looks like (Calibre-issue.PNG).
Previously, Calibre 4.8 running in the Windows 7 VM had no such problem.
VirtualBox is v. 6.1 (running in Linux Mint 18.3) and has the 6.1 guest additions CD installed.
Has anyone seen this sort of thing?
