Open the URL 2. Open page number 2 3. Compare it with what you see in e.g. Evince Also, other pages have different bullet symbols. What is the expected behavior? English text is shown What went wrong? Strange symbols are shown, bullets are not displayed. Does it occur on multiple sites: N/A Is it a problem with a plugin? N/A Did this work before? N/A Does this work in other browsers? N/A Chrome version: 51.0.2704.79 Channel: stable OS Version: Ubuntu, openbox, #53-Ubuntu SMP Wed Jul 27 16:06:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Flash Version: Shockwave Flash 22.0 r0 Haven't tested on other platforms. Maybe the bullets caused problems, or missing fonts. But if the fonts are the problem, then does Evince show the characters properly?

Thanks for the report. I am unable to reproduce the above issue on Ubuntu 14.04 with chrome latest stable version '52.0.2743.116'. I would request you to please try the same on latest chrome stable version and let us know if the issue persists. Attach is the print-screen.

Works for me with the same set up at comment 2. It sounds like you are 1 version behind, and you are using Chromium. (Presumably Ubuntu's package?) Can you try installing Google Chrome and see if it has the same problem? Or at least try to install it and see if apt-get asks you to install more font packages. Then install the request font packages.

I was referring to the Depends, not Provides. Do you have any special fontconfig configurations? What truetype font packages are installed? Are there any local fonts? What version of Ubuntu?

To Comment 2, Comment 5 The fontconfig is the default one. I have been using Infinality once on this system, but after that I made a reset and restored the original configuration, removing even the PPA with all the custom packages, hence, original packages were reinstalled. I might check checksums of the files if You could tell me the exact list of fontconfig packages. Looks like everything, which the google-chrome-stable package depends on, is installed. Local fonts are the Windows ones, residing in ~/.fonts ... Eveentually, the bug vanished 1 day later. I don't know whether any updates were installed, but now neither Chrome nor Chromium show the bug. I.e. the complete document is displayed correctly.

Well, it looks like we stumped on the floor and the bug has ran away in fear. |
