Public bug reported: Ubuntu 16.04 Developement version Xenial.
Cinnamon version: 2.8.6-1ubuntu1 Basically, using steam, in random behaviours I'm unable to see in the Cinnamon window list usual steam conversation chat window with people, basically, the window in the window list applet appears once and in random behaviour it disappears. However, I'm able to see it in the ALT+TAB list. But not in the panel Window list, I have to reload steam.
