Thanks for this. Very useful.
I played with settings again. The key change seemed to be turning whiten apps off.
Still leaves me with the font issues. Some have everything in a horrific outline font and others don’t. That was the issue with dark mode in QuickEdit.
My overall impression of the Boox is that it is very good and useful for what it does well, but is a very high friction gadget otherwise. That’s not a problem for me - I already have an excellent conventional colour tablet; so I’m not giving it the attention a high friction device would usually receive.
I use the Boox for reading (Kindle, PDF mostly) and writing (the Notes app for writing/drawing and a few editors); for these it is more effective than alternative gadgets. I will use browsers but as little as I can manage.
