I use the Ozone build of Chromium, available on AUR - https://aur.archlinux.org/packages/chromium-ozone/

It's a painful first compile, but the only issues I've hit have been a few menus in the extension debugging screens that are too small.

Well, not your typical end user routine I guess. I’d like that in mainstream distros please, without having to edit .desktop files to shove in all the commandline flags.
