On the latest AMD driver which lines up with when the issue started.
I've tried using the --disable-gpu flag with ebook-viewer.exe to force software rendering but no luck there (as there doesn't seem to be an equivalent option with calibre-debug.exe ?) I tried setting an environment variable (in Windows 10) but that hasn't had any effect either. Is there any other method of forcing software rendering?
Thank you for your time!
