View Full Version : Gnome 3.26, fractional scaling and firefox

12th October 2017, 12:42 AM

I'm using the current F27 beta, enabled fractional scaling like described here (http://www.omgubuntu.co.uk/2017/09/enable-fractional-scaling-gnome-linux) and set my monitor to 150%. GTK3 applications work fine including epiphany and libreoffice. Non-GTK3-applications are scaled up and get a blurry interface, including chrome/chromium, the mother of GTK “The GIMP” (GTK2), inkscape (GTK2), VLC (Qt) and, to my astonishment, firefox. firefox is based on GTK3 since its Version 46.0 (see ReleaseNotes (https://www.mozilla.org/en-US/firefox/46.0/releasenotes/)).

Question: Does anyone know, how I can get firefox to look as nice as epiphany with fractional scaling on 150%?

I would be fine with disabling the scaling for a particular window-class or similar and scale ff up with layout.css.devPixelsPerPx. This setting would also be interesting for applications to connect to remote-desktops which have their own scaling.

OK, the thing is not GTK3 but running on wayland natively – not with xwayland. There is a firefox-nightly-variant for that but see yourself in the screenshot ;)

Fixed the thread title to say 3.26 instead of 2.26
