Do you make any progress? I tried to search the reason for my own. I downloaded the source and compiled it successful. But Visual Studio crashed whenever I start to debug chromium. How do you debug and fix code under Windows what do you use??

This is probably a Windows synthetic bold issue, but I can not yet be sure. Please attach a PDF produced by the "Save As PDF" workflow. https://github.com/HalCanary/howto-save-as-pdf

Yep, that looks like the synthetic bold typeface problem. I see two identical fonts embedded, so Skia's font manager assigns them different fontIDs, they rasterize differently, but SkTypeface::openStream returns the same data. SkTypeface::onGetAdvancedTypefaceMetrics() should return kOther_Font for these synthetic typefaces.

The following revision refers to this bug: https://skia.googlesource.com/skia.git/+/0b7758236ca81337aa465a9f61cf466f03718862 commit 0b7758236ca81337aa465a9f61cf466f03718862 Author: bungeman <bungeman@google.com> Date: Tue Sep 13 21:03:54 2016 Simulated fonts aren't TrueType fonts. Some font back-ends provide simulated fonts such as fake bold or fake oblique. These fonts should not be reported as TrueType, since the font data isn't what is actually used to draw the glyphs.

Fixed, needing verification.

As in, fixed in 55.0.2861.0 and newer. i.e. Check Chrome Canary in a day or two.
