This doesn't repro on my windows workstation. I tried with same version of Chrome and MR as above.

What versions of Windows does this repro or not repro on?

It is Windows 7 on my workstation that doesn't repro this issue.

Verified this repros on Windows 10 and Windows 8, but not Windows 7. Continue investigating.

Confirmed that the issue is caused by the failure calling SystemParametersInfoW()[1], which results a null typeface created by calling SkTypeface::MakeFromName()[2].

The issue doesn't repro with "--no-sandbox".

DW last resort font default name not necessary.

Currently in SkFontMgr_DirectWrite when trying to find some last resort
font SystemParametersInfoW failing is considered a fatal error and so
onLegacyCreateTypeface will return nullptr. Instead, treat failure of
getDefaultFontFamily as ignorable and continue to the default default.

bungeman@: With the above patch, now the text message is able to be displayed on Windows 8. But the ellipsis mark turns to a square on Windows 8.

The family name of the typeface returned by SkTypeface::MakeFromName("sans",...) is SimSun-Ext8.

Any ideas?

Well, you're getting the default default font, which is just some font on your machine without any regard to anything. Are you requesting whatever the user set their default font to in settings? There is no magical font named 'sans'. How are you shaping this text? How are you doing font fallback? Where is the code doing the actual draw? If you're calling into Skia with anything other than kGlyphID_TextEncoding set on the paint / text blob you're probably holding it wrong.

bungeman: I don't think this is an issue with how we're using the API (though, we'll check on that kGlyphID thing you mentioned). "sans" is something all platforms should provide a reasonably-close default sans-serif font for. In fact, on Win8/10, when running Chrome with --no-sandbox, "sans" does map to a perfectly good font. It also works on Win7 and all other platforms. This suggests the font-lookup mechanisms are broken because of the sandboxing: Perhaps the platform integration code is making calls into the OS library that fail while in a sandbox? How do we fix this? Why are Skia fonts broken, but not Webkit fonts? Do they use different integration w/ the OS?

FWIW, the Chrome Windows platform team pointed us as this: https://cs.chromium.org/chromium/src/content/child/dwrite_font_proxy/dwrite_font_proxy_win.h?rcl=8319b23bcb1895fea5a4a308837c100beb42f068&l=28 Unfortunately, the original author of that code has since left the Chromium project.

Addendum to comment #10: To be clear, a reasonable font for "sans" is found and works *with* sandboxing turned on; on Win7, and all other platfroms.

Why do you think "sans" is the name of a valid font? This is a web browser-ism, the system doesn't have to have (and often doesn't have) any match for "sans". Even with FontConfig having a "sans" match is just a common convention. "sans" doesn't get you a sans-serif font or match anything on Windows 7, you were previously just getting whatever the default UI font as a fallback (because there was no "sans" font) which doesn't need to be sans-serif or even exist. When Blink needs a font for "sans" it uses the font set by the user in preferences. It will also do font fallback for any glyphs not in the current font.

Update: Tried using gfx::RenderText to render the message instead, but crashed on Windows 8.1 at this DCHECK: https://cs.chromium.org/chromium/src/base/win/win_util.cc?rcl=d8ee83729c29c767b7465dc23940b83a8a88fb89&l=300
Seems the same problem: sandbox blocks the access to SystemParametersInfo() on Windows 8.1.

Media Remoting: Add interstitial elements to media element shadow dom.

This CL add the following elements to media element shadow dom when
media remoting starts.
1. Add a disable button to allow user stop remoting and fall back to
tab mirroring. This is to solve the accessiblity regression caused by
media remoting with lacking support for closed captions.
2. Add a background image, cast icon and a text message. These three
are currently rendered as a video frame in media renderer. Move them
to media element to keep consistent with the disabel button and solve
the font renderering issue on Windows 8/10.

The old interstitial (rendered as a video frame) will be removed in a
later CL.
