Re-opening because this has apparently slipped into the beta channel. I'm
not sure if fixes were merged yet, but we need a new beta push with them.

For beta users being newly affected by this bug, please see comment #11 for
workaround.

So now, in VNC, which I have used for years, I hit the DCHECK in
desktop_screen_x11.cc:67, where my |device_scaling_factor| is only 0.78. Is
that a configuration error on my side or a problem with the new code?

https://code.google.com/p/chromium/issues/detail?id=473089

thestig, in your font-config-info there’s:

X11 display info:
screen pixels 1260x740
screen size 427x251 mm (74.95x74.88 DPI)

I’m not sure why VNC sets this and how dynamic it is, i.e. whether VNC
updates when you connect to it from a different display. In any case, you
should configure VNC such that it tells applications to use 96 DPI.
Possibly open a bug upstream with VNC if there’s no knob to twiddle.

I am still seeing this with google-chrome-unstable 44.0.2383.0 dev (64-bit)
on Debian Sid/KDE. Using --force-device-scale-factor fixes the issue.

Can you provide more detail? I.e. the output of
https://github.com/derat/font-config-info on your machine, and to which
value you’re forcing the device scale factor, also which hardware you’re
running on…?

Some more info. My machine is a Thinkpad X220...

I'm running KDE 4.14.2 with desktop effects turned on.

Another issue I'm seeing is that with Chrome when I load a new page or
switch tabs the content doesn't display inside the view port until
something dynamic happens, like the page scrolls, I move my mouse over
something, the content moves, etc. Turning off desktop effects in KDE fixes
the rendering issue.

Using --force-device-scale-factor with no other arguments beyond fixed both
the scaling issue and the rendering issue.

I do see the scaling issue with google-chrome-beta 43.0.2357.65 beta and
google-chrome-unstable 44.0.2398.0 dev, but not with google-chrome
42.0.2311.152. The rendering glitch I'm only seeing on unstable.
Additionally the scaling issues is not just tied to the UI of Chrome but
also content displayed within the view port.

Hope that information is helpful. Thanks.

Anddddd I take that back, my rendering issues are not resolved by
--force-device-scale-factor sadly.

I don’t think the rendering issues are related, so please open a separate
bug for that.

oshima recently submitted https://codereview.chromium.org/1136913005/ as
revision 330212. Once that’s in a release, please confirm whether the issue
still exists or is fixed.

The following revision refers to this bug:

https://chromium.googlesource.com/chromium/src.git/+/da20b3fc0aed6674160b02eba4919f6ec2379ec7

commit da20b3fc0aed6674160b02eba4919f6ec2379ec7
Author: Michael Moss <mm...@google.com>

device scale factor detection: use gtk-xft-dpi consistently

Before this CL, we used either gtk-xft-dpi (UI fonts) or the physical DPI of
a more or less random display. This CL consistently uses gtk-xft-dpi which
is the better alternative: users can directly influence it (by changing the
Xft.dpi X resource, or via their gtkrc).

See also https://github.com/derat/font-config-info for displaying your
current system settings.

This is a re-do of https://codereview.chromium.org/1070433002/, but with
https://codereview.chromium.org/1084453002/ applied (fixes content_shell).
