Viewer in 4.2 opens with only blank white page
Using Mac OSX Catalina when opening a epub book in Viewer mode I only get a white, blank page with no text. I can go back to the calibre library on my hard disk and open the same epub with a different reader and all is there. Any ideas of what to do?

I'm not using an external GPU. It is a new Mac Pro computer.

The only known reason for this is using an unsupported/external GPU. If you arent then you can try turning off hardware acceleration, as described here: https://doc.qt.io/qt-5/qtwebengine-debugging.html
