Don't use it. The networking is broken, and messages do not get through. The minimum window size is even infuriatingly larger than before. The ALSA audio is broken and does not work. And it produces annoying popups and upsells which cannot be turned off since I can't work out what they're called in the config.
It is actually unusable to the point that I couldn't hold a text conversation or make a voice call to the test-bot.
I'm very disappointed, after the long wait for an upgrade to the Linux client, they have actually made it worse, not better, in every important respect.
