MATE: 1.20.1 with Static Application Switcher.
I just updated two different laptops to 18.04 and they both have the same new behavior. Previously, when I hit ALT-tab the switcher would highlight the border of the selected window. I could cycle through multiple apps until the border of the window I wanted was highlighted. This was useful, say, when I had multiple xterm windows open. After the update there is no animation.
I've fiddled with all sorts of app switcher settings but can't seem to get that behavior back. Is it gone or is there a way to get it back?
