Dashed line rendered solid in Chromium

[pcworld]

Page 2 of this PDF contains dashed lines, which are rendered solid in Chromium 43 using this this online demo of pdf.js, but fine in Firefox 38.0.

According to #1012, a similar issue was going to be fixed with #2429, however I'm not sure if this is the same issue here.

I reduced the test case using the technique that I documented at #5043 (comment).

This is a recent bug in Chromium (since version 43):

This is a recent bug in Chromium (since version 43)

The linked bug affects versions starting from at least 34. It was marked as a duplicate of a bug that is from July 2013.
So shouldn't either earlier Chromium versions be affected as well (I haven't tried) or is this a different bug?

@pcworld The bug from my previous comment was filed 25 minutes ago by me. I only referred to the other bug at PDF.js to explain how I created the reduced test case (in case you want to create one yourself, in the future).

@Rob--W Sorry, I mixed up the issue tracker links then.

@Rob--W This seems to have been fixed upstream. Could you verify this and close the issue if it is indeed fixed?

[Rob--W]

@timvandermeij This has indeed been fixed upstream and merged back to 44, but not 43. I've verified that the bug has been fixed in 46.0.2455.0 (and therefore also in 45 and 44).

Within a few weeks, Chrome will upgrade to 44. Since there's nothing that we (as PDF.js devs) can do to fix this issue in 43 (except for patching the .save/.restore methods), I'll close the bug.
