I noticed that some apps (Google Chrome, Viber, VKAudioSaver) have problems with HiDPI dispays (everithing is too small). Other apps work nice. Strange thing is that Cromium works good (with some issues) and Chrome does not.

Is there a way to fix it?

No, there is no way to fix this to make applications scale automatically on HiDPI displays. Each application/GUI toolkit needs to be updated to cope with HiDPI. There was some talk of supporting legacy applications by automatic scaling up (as OSX does) but it has not been done yet.

  • Thanks! Is there a list of supported GUI toolkits? How come Chromium supports and Google Chrome not? I thought they use same GUI toolkit. – umpirsky Jun 13 '14 at 14:31

    QT and GTK should both support HiDPI now, however, applications probably need to be updated to use the newer versions. Chromium and Chrome do use the same toolkit, but Google currently disable HiDPI support when they build Chrome on Linux, probably because it does not work 100% correctly yet (see chromium bug #143619) – bain Jun 13 '14 at 15:08

    btw one of the people who is responsible for HiDPI support in Ubuntu has blogged on the issue: The future looks very small. As for automatic scaling of apps he says, " I’d really like a system-wide fix, but the reality that isn’t going to happen. Not this year, I’m afraid." – bain Jun 13 '14 at 15:11
  • Actually, you can run apps with a defined scale factor by using run_scaled. – Pablo Bianchi May 22 '19 at 00:20
