Inconsistent PDF rendering in different programs after running GhostScript #561

Open tomaas-zeman opened 2 weeks ago

I have never seen this before but for some reason, when opening the released PDF in a Chrome tab (internal PDF viewer) and in MacOS PDF viewer, I get different results

Building the file locally without any optimizations produces a file that looks correct in both viewers.

Only after I run optimize.sh and GhostScript tool, I can see that problem again.

Ghostscript 10 utilizes some bleeding-edge optimizations. Perhaps not every PDF reader is capable of rendering them properly. Mind trying the same with Ghostscript 9 to see if you get the same result?

GS9 didn't help. It's either shadow or transparency issue I think but I was not able to find anything that could help to fix it. It seems more like an issue on the MacOS PDF viewer side.

Not sure if it's worth to spend more time on this - the solution is to use different apps which are quite common
