Dashed
styling gets erroneously applied to the head of an Arrow
when exported to PDF in version 12.1-12.2 on Mac -- it looks fine on the screen and when exported to PNG (also fine for versions 10.0-12.0).
testfig = Graphics[{Blue, Dashing[.03], Thickness[0.008], Arrow[{{0, 0}, {0, 1}}]}]
Export[StringJoin["testfig.png"], testfig, "PNG", ImageResolution -> 300];
Export[StringJoin["testfig.pdf"], testfig, "PDF"];
Bug? Workaround?
Possibly related (although the fix doesn't work)
