Hello, I initially thought that I would submit it as a bug report, but as my question pretty much is « the Hangouts app doesn't work at all on this navigator not listed in the Solving Technical Issues wiki page », I'm not sure that it would be in accordance with the rules. But still, this is very weird: I use Chromium on a Debian Sid 64bit machine (the About section of my navigator indicates Version 34.0.1847.116 Debian jessie/sid (260972)), the Roll20 app works perfectly, except when used with Hangouts - the screen is just completely blank. What makes me think that this is weird is that Chrome and Chromium have exactly the same layout engine, the same design, Google Chrome is basically Chromium with Google-ish features (especially since I have added the Chrome PDF reader into my Chromium installation, and since I have Flash installed and working (the Adobe test page returns « You have version 11,2,202,332 installed »)). I have never seen an app work on Google Chrome and not Chromium, so I suspect that there must be a hardcoded browser test (or something else easy to debug). Ironically, supportdetails.com doesn't even seem to see the difference between Chrome and Chromium: Web Browser Chrome 34.0.1847.116 Javascript Enabled Flash Version 11.2.202 So, if you could take a look at what causes this issue, that's be nice for open-source enthusiasts such as myself :-) Best!
