I used to use Skype for Linux version 5.xxxx on Debian/stable. Today, an automatic upgrade to version 18.104.22.168 was installed (after an apt-get dist-upgrade). I had to launch Skype and type my credentials again, but Skype remains blank. All there is is a white window with a menu bar on top, but nothing happens when I click into that window or choose one of the menu items like "Help -> About Skype", "File -> View Profile...", "Tools -> Settings...".
Could this be fixed, please?
