I am trying to set some background text properties in my Emacs buffer. For instance,
(set-text-properties pos1 pos2 '(face '(:background "cyan")))
But I cannot get it to work. I think I have a clue why it does not work:
I am also using a major mode that uses (setq font-lock-defaults '((some-font-lock-keywords)))
If I comment out that assignment to font-lock-defaults it works fine.
