Note the page zoom was confirmed to be at 100% in both Chrome dev and Chrome stable in the attached screenshot(s).

Tested the issue on ubuntu 14.04 carbon X1 using chrome M58 #58.0.3029.110 and M60 #60.0.3103.0 and issue is reproduced with the following steps :

1. Had set the machine dpi to 2 and page zoom is 100 % .
2. Installed chrome dev M60 #60.0.3100.0 and chrome stabel m58 #58.0.3029.110 
3. Compared both chrome stable and dev and didn't observe any difference.

@cole.mickens-- Could you please check steps and attached screenshot and confirm us if we had missed any steps in reprodcing the issue .

Thanks!

Yes, this is missing repro steps.

You need to use gnome-tweak-tool to change the font scaling to 75%. See my attached screenshots.

Tested the issue on ubuntu 14.04 using chrome M58 #58.0.3029.110 , using the tweak tool , tried changing the fonts scaling and unable to find the option of chnaging window scaling in windows.

Attached screencast for reference.

@cole.mickens-- Could you please check attached screencast and confirm us if we had to enable any other settings to find window scaling options.

Thanks!

I don't know what else to say. It's trivial to repro this. I've given the exact steps and provided screenshots of the settings that are necessary to trigger the repro.

It may be necessary to use a distro that is not 3 years old.

This is being reported by another person as well: https://bugs.chromium.org/p/chromium/issues/detail?id=716135#c26

Gtk: Consider font dpi when calculating device scale factor

Gtk2 did not have a global window scaling setting (so the only way to
scale up widgets was with a custom theme).  However, it did allow font
scaling with gdk-xft-dpi (backed by XSetting Xft/DPI).

Gtk3 adds (non-fractional) global window scaling with
gdk-window-scaling-factor (XSetting Gdk/WindowScalingFactor).  To
ensure that fonts were not scaled up twice (once from
gdk-window-scaling-factor and once from gdk-xft-dpi), a new setting
was added in [1] that overrides gdk-xft-dpi: gdk-unscaled-dpi
(XSetting Gdk/UnscaledDPI).  gdk-xft-dpi was kept around for
compatibility with apps like Chromium that still need it.

When modifying these settings, an invariant should be maintained:
gdk-xft-dpi = gtk-window-scaling-factor * gdk-unscaled-dpi.  Chromium
should have been able to keep using gdk-xft-dpi, but this invariant is
violated when changing the settings using gnome-tweak-tool, where I
have gdk-window-scaling-factor = 2, gdk-unscaled-dpi = 98304, and
gdk-xft-dpi = 98304 (gdk-xft-dpi should be 196608).

[2] changed Gtk builds to use the window scaling factor, which is
incorrect because it did not consider font scaling, making fractional
scaling impossible.

This CL takes gdk-unscaled-dpi into the calculation as well, and
continues to fallback on using gdk-xft-dpi if the other variables are
unavailable, which can happen on Gtk2.

Should be fixed now.  If any users still see the issue in the next beta release, please comment here and I will reopen this issue.
