No icon when doing Alt-Tab (switching applications) about ssr HOT 3 OPEN

It works for me ... are you using the default desktop environment (Unity) or something else?

You can try to run

gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor

But normally this shouldn't be needed, it should be done automatically by the package manager.

I am using Unity.
I tried

sudo gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor

but that had no effect.
I do have a missing icon for some other applications, e.g. Kazam, so it could be some general issue with my system.

I think so. I'm not sure where Unity gets the icon from, since there are actually two icons: the one for the desktop entry (this is what you see in the dash and probably the sidebar), and the icon for the actual window. But on all the systems I've tried, they both work.
