Try M-x my-line-glitch-repro in both a textual and graphical session,
then put point on the space displayed as a 80 characters wide line. In
the graphical instance the line will be hidden (with the beginning being
displayed *in* the cursor's rectangle in reverse video), in textual
instances it's still visible (assuming your terminal supports
underlining).
