After opening the activity switch I could not close it anymore. I tried to click on the desktop background, but that doesn't close it. There is also no X button like in the widget adding panel. From the neon5 beta. Reproducible: Always Steps to Reproduce: 1. open activity switcher from the top left button 2. try to close it by clicking on the desktop background Actual Results: Doesn't close. Expected Results: Should close.
I think close button was there.
This has been fixed by Marco in plasma-frameworks today, it's a problem with the focus, also affecting popups in the panel. *** This bug has been marked as a duplicate of bug 334819 ***
