Public bug reported:
I have a unity desktop in Ubuntu 16.04 with 1 workspace. When I press
Alt+Tab, I do not see in the switcher windows of some apps. Franz
(http://meetfranz.com/) is one example. Also the triangle beside its
icon in launcher is only contoured, and not filled like for other apps
(see screenshot).
Curiously enough, when I launch CompizConfig, open Ubuntu Unity Plugin
settings, and in the Switcher tab switch some checkbox on and off again,
i.e. "Switcher strictly changes between applications", then the missing
windows appear in the switcher. The triangle remains only contoured
though.
