Ghostscript v8.63
This works for me with 904. Since this was reported some time ago and was against 8.63, it undoubtedly has been fixed. Note that the bug report was sort of suspect since it mentions 'multithread', but the command line given in comment #3 didn't specify -dNumRenderingThreads=2.

I have missed to specify the NumRenderingThreads as I copied my default usage flags. But the problem was indeed happening on multithreaded usage. Since this and other problems with PDFs with transparency I have stopped using Ghostscript. If I gather some time will check again rendering results. |
