[Pkg-chromium-maint] Bug#871542: chromium: Chromium 60 UI is huge on HiDPI displays

[Andreas Kloeckner]

Package: chromium
Version: 60.0.3112.78-1
Severity: important

Dear Maintainer,

As of Chromium 60.x, the browser UI (address bar, back buttons, etc) is
drawn at a disproportionately large size on my MS Surface Pro 3
(2160x1440). See this screenshot:

vs Chromium 59 for comparison:

Google Chrome 60.0.3112.90 is unaffected, i.e. drawn at roughly the same
size as Chromium 59.x.

I'd be much obliged for any advice.

Thanks!
Andreas
