Confirmed.  I used this sample code:

graphics_toolkit fltk
h = patch ([0 1], [0 0], 'r', 'linewidth', 5);

This may be related to bug #38779 and bug #47677.

With the Qt or fltk graphics toolkit, the following displays nothing:

h=patch([0 1],[0 0],[0 0 0])

while with gnuplot, it appropriately displays a black line from left to right (as does Matlab).
