@Andrea,

I don't understand what you meant by "you can simply can add a special
style class if needed."

I have attached a standalone testcase which demonstrates the bug. The
testcase is a toplevel window which contains a single widget -- a
subclassed EventBox that renders a handle centered within the window.
Please note that the only drawing in this testcase -- including the
background -- is done by GtkRenderHandle *which is rendered by the unico
engine*.

The testcase styles the widget with a css fragment defined in main() as
faux_theme.

Feel free to "add a special style class" to the faux_theme definition so
that the testcase output matches the reference image which I will also
attach.

Title:
  Handle not rendered properly if border-width = 0

Status in Light Themes:
  Invalid
Status in The Unico Gtk+ Theming Engine:
  Confirmed
Status in “gtk3-engines-unico” package in Ubuntu:
  New

Bug description:
  When rendering handles (unico-draw.c: unico-draw-handle), if the
  current style context has border-width = 0, the handle is not rendered
  properly. This happens because the line-width is style-matched to
  "border-width" in unico_get_line_width(), which in turn, means that
  some of the lines are not stroked and the geometry calculations are
  off.

  When rendering handles, often the border-width will be set to 0 so
  that the entire background will be wiped to the correct pattern
  (without leaving a border artifact - this happens on oneiric with
  gnome-panel and the Radiance theme).  The same problem exists when
  rendering separators as well.
