[Pkg-chromium-maint] Bug#845785: chromium crashes on certain websites

[Ara Keary]

Dear maintainers,

same here, updating to 54.0.2840.101-1 makes chromium crash on the
website gmail.com, with "Aw snap" message; please find below the
message found when launching chromium from command line.

Reverting to testing version 53.0.2785.143-1 solves the issue.

I suspect the problem is coming from hi-resolution (my screen is HD
3200x1800) ; indeed:

 - with 53.0.2785.143-1 i have to start chromium with the command
     chromium --force-device-scale-factor=1.8
   otherwise scaling is wrong (fonts too small).

 - a previous 53 version on unstable was also crashing on gmail.com with "Aw
snap"

 - for the version 54.0.2840.101-1, starting either from 'chromium'
command or 'chromium --force-device-scale-factor=1.8' gives the same
correct scaling.

Best,

Ara
