Notice that the fringe close to scroll bar is much wider than the
other fringe (see screenshot).  This appears to depend on the font
size, as for smaller fonts, the effect is not that noticable.  For
example, with Gtk+ and lucid, monospace-19 shows this rather well,
but for monospace-20, there is little difference.  But for
monospace-20 the fringes are much smaller than for monospace-20.
Why?

Hasn't it been like that since this change?

Exactly.  For more info, see the thread starting from
http://lists.gnu.org/archive/html/emacs-devel/2007-03/msg00295.html


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.
