+Some web pages may require additional fonts to display properly.
+Try installing some of the following packages if some characters

+- media-fonts/arphicfonts

+- media-fonts/noto
+- media-fonts/ja-ipafonts
+- media-fonts/takao-fonts
+- media-fonts/wqy-microhei
+- media-fonts/wqy-zenhei
+
+To fix broken icons on the Downloads page, you should install an icon
+theme that covers the appropriate MIME types, and configure this as your
+GTK+ icon theme.
+
+For native file dialogs in KDE, install kde-apps/kdialog.
+
+To make password storage work with your desktop environment you may
+have install one of the supported credentials management applications:
+- app-crypt/libsecret (GNOME)
+- kde-frameworks/kwallet (KDE)
+If you have one of above packages installed, but don't want to use
+them in Chromium, then add --password-store=basic to CHROMIUM_FLAGS
+in /etc/chromium/default.

+Subject: [PATCH] GCC: fix access to private class in blink::DocumentLoader
+
+Friend does not work with anonymous namespaces. Therefore,
+DocumentLoader::DecodedBodyData is private for struct
+SameSizeAsDocumentLoader. Add a wrapper in blink namespace
+to make the class visible in anonymous namespace.
