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. Created attachment 56762 [details]

Moving to cairo renderer then Thought it works for me in the cairo renderer, maybe some cairo library issue? 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 Created attachment 60940 [details]
Minimal TestCase

Created attachment 56760 [details] 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.
