UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36 Steps to reproduce the problem: On a computer with 1920x1080 resolutions (144x144 DPI) start Google Chrome with the parameter "--force-device-scale-factor=1.00" and notice how tiny the font size is set. Below you have my font-config-info output: GtkSettings: gtk-font-name "Noto Sans Regular 8" gtk-xft-antialias 1 (yes) gtk-xft-hinting 1 (yes) gtk-xft-hintstyle "hintfull" gtk-xft-rgba "[unset]" gtk-xft-dpi 147456 (144,00 DPI) GTK 2.0 styles: GtkLabel "Noto Sans 8" GtkMenuItem "Noto Sans 8" GtkToolbar "Noto Sans 8" GSettings (org.gnome.desktop.interface): font-name "Noto Sans Regular 8" text-scaling-factor 1,00 X11 display info: screen pixels 3840x1080 screen size 677x191 mm (144,07x143,62 DPI) X resources (xrdb): Xft.antialias "1" Xft.hinting "1" Xft.hintstyle "hintfull" Xft.rgba "rgb" Xft.dpi "144" XSETTINGS: bash: dump_xsettings: command not found Install dump_xsettings from https://code.google.com/p/xsettingsd/ to print this information. Fontconfig (Noto Sans 8): requested size 8 points family Noto Sans pixelsize 16,00 pixels size 8 points antialias 1 hinting 1 autohint 0 embeddedbitmap 1 hintstyle 2 (medium) rgba [no match] Fontconfig (default pattern): antialias [no match] hinting 1 autohint 0 embeddedbitmap 1 hintstyle 3 (full) rgba [no match] Fontconfig (default match): family Liberation Sans pixelsize 24,00 pixels size 12 points antialias 1 hinting 1 autohint 0 embeddedbitmap 1 hintstyle 2 (medium) rgba [no match] Fontconfig (non-family/size defaults): antialias 1 hinting 1 autohint 0 embeddedbitmap 1 hintstyle 2 (medium) rgba [no match] What is the expected behavior? Chrome should respect what default desktop environment font size has set as default. What went wrong? Google Chrome ignores the DPI setting that I tried to set in ~/.Xdefaults or ~/.font.conf. Google Chrome ignores the GTK default font size (or KDE setting for that matter). Did this work before? N/A Chrome version: 57.0.2987.98 Channel: stable OS Version: KDE Neon Flash Version: I ran the same version of Google Chrome, with the same "--force-device-scale-factor=1.00" parameter on Windows 10 and there it looks OK. I expect the same behavior on Linux.
