The buffer text itself is not the only data to control the display, there
are also properties that refer to regions of that text, and in fact that
is the part that matters here.  It is certainly possible to check for at
least the presence of extra properties in a line without walking each
character one by one.

AFAIR, Emacs display code already includes this optimization.

I'll believe you anything you want if you can fix the problem.
