Howdy! I found that the single space character after certain[1] entities and inline LaTeX fragment is fontified as `org-block'. This is invisible with the default Emacs non-theme, but it is visually confusing when a theme[2] is loaded that gives `org-block' non-transparent background.
[1] Fontification is okay if the entity ends with {}. [2] For example, Prot's popular themes color the background. Visually, the problem is: foo \alpha bar ^------ this space character is fontified as `org-block' x $y$ z ^------ this space character is fontified as `org-block' Rudy -- "Programming reliably -- must be an activity of an undeniably mathematical nature […] You see, mathematics is about thinking, and doing mathematics is always trying to think as well as possible." --- Edsger W.
