You can also run Chromium with --force-device-scale-factor=1.

Upstream did revert half of a patch. You can try to compile the program
here:
 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763421#125

If it reports anything else than 98304, the bug likely steems from the
fact that the computed scale factor can only be an integer due to a
"stable" change. If it is 98304, well, I don't know.

Either way, if you don't have HiDPI at all,
--force-device-scale-factor=1 is safe to use.
