There is something off with the calculations for the frame size then.  Check 
attached screen shots.  The right fringe is not visible.

The frame size calculation uses f->scroll_bar_actual_width which in this case 
is 16.  But the finge padding must be 14 pixels (font width is 15, so I assume 
padding to 30 is done).

In what frame parameter or struct frame member is this padding seen if not in 
scroll_bar_actual_width?

Please don't suggest using columns * font width, it would just make the 
restriction of integral font width harder to remove.
