I have done some testing and the display works correctly with clear text on

I have had a look at the changes but I can't find anything that might cause

Any ideas?

Can you please try to bisect the problem?

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
