PDF file to reproduce the problem

After attempting to render attached PDF, one should see an arrow at the end of all edges connecting vertices (which holds for xpdf). However, poppler-rendered images contain arrows only for upper edges, and (from some strange reason) semi-transparent arrow when using specific rotation.

LaTeX source file of the testcase.

Attaching source file to produce testcase PDF. When changing 'in' angle at line:

			(VN1) edge[out=-35,in=-145] (VN3)

one can get variety of cases with visible/semi-visible/invisible arrow.

Please attach a screenshot.

Also please check if pdftoppm and/or okular give you correct results.

Moving to cairo renderer then

Thought it works for me in the cairo renderer, maybe some cairo library issue?
Comment 6 aatdark 2012-05-02 15:05:05 UTC
i created a more minimal LaTeX example with just 2 arrows. Both arrows are created the same the only difference:

the first (broken) arrow points toward up,right
the other arrow points toward down,right

so it depends on the direction of the arrow!

Xpdf,okular both render them correctly

Evince 3.2.1
