This appears to be https://bugs.debian.org/833074 manifesting with GNOME
3 as well, the workaround Tollef provided works there but is clearly
awful.

This is a substantial regression in functionality on fairly common
hardware (I'm using a Dell XPS 13 (2015)) so I'm not lowering the
severity to merge, there's an awful lot of modern laptops with HiDPI
screens and currently the default behaviour results in an illegible UI
on these systems.

https://bugs.chromium.org/p/chromium/issues/detail?id=515984 upstream
may be related, though the workaround at the bottom does *not* work for
me (I suspect --force-device-scale-factor=1.8 may be needed but I've not
tested yet).
