I see in your capture, you use cleartype (red/blue effect) and this force the font smoothing. Problem is when set on the system No cleartype, No fontsmooth; it's respected in the chrome tab, all website, but not in Google Apps popup.

-disable ClearType (no work fine for all LCD, The fonts are less fine, less clear and with a fat/blur effect)
-disable smooth font (add blur effect for smooth)
-compare in the new tab keep.google.com and apps google Keep (from webstore)  or other apps.

and check again. Chrome respects this configuration for web pages and shortcut in desktop to new windows, but not for the chrome application

app_window_contents.cc is missing a call to renderer_preferences_util::UpdateFromSystemSettings(content::RendererPreferences* prefs..). Usually PrefsTabHelper does this, but only tabs have those.

AppWindowContentsImpl::Initialize needs to look something like


void AppWindowContentsImpl::Initialize(content::BrowserContext* context,
                                       content::RenderFrameHost* creator_frame,
                                       const GURL& url) {
  ...
  Observe(web_contents_.get());
  content::RendererPreferences* render_prefs =
      web_contents_->GetMutableRendererPrefs();
  renderer_preferences_util::UpdateFromSystemSettings(render_prefs,
                                                      context,
                                                      web_contents_);
  render_prefs->browser_handles_all_top_level_requests = true;
  web_contents_->GetRenderViewHost()->SyncRendererPrefs();
}


but renderer_preferences_util is in src/chrome which needs to call via ExtensionsBrowserClient

+avi - do you have any thoughts about adding a ContentBrowserClient method for this? (i.e. something like

void ContentBrowserClient::FillDefaultRendererPrefs(BrowserContext* browser_context, content::RendererPreferences* renderer_prefs);


A lot of other font preferences are set in 

void ChromeContentBrowserClient::OverrideWebkitPrefs(RenderViewHost* rvh, WebPreferences* web_prefs) - https://cs.chromium.org/chromium/src/chrome/browser/chrome_content_browser_client.cc?q=ChromeContentBrowserClient::OverrideWebkitPrefs&sq=package:chromium&l=2373

So a more robust alternative to #c7 might be to make setting default RendererPreferences the responsibility of the ContentBrowserClient. This could allow a WebContents to pick up a meaningful default set of RendererPreferences rather relying on the client code to invoke renderer_preferences_util::UpdateFromSystemSettings().

There is some other important stuff there - https://cs.chromium.org/chromium/src/chrome/browser/renderer_preferences_util.cc?type=cs&q=UpdateFromSystemSettings&sq=package:chromium&l=85

This approach would mean the "Manage People" account picker dialog also gets the correct values, which #c7 doesn't attempt to solve.

+jam for his thoughts

I think this would be a reasonable approach; John, what do you think?

same problem with dev Tools(F12), all menu and setting are blur
