Steps to reproduce the problem:

2. Take a screenshot

What is the expected behavior?
Just a screenshot is taken

What went wrong?
Tab+Alt Switcher animation goes into a endless loop without further input from user

Did this work before? N/A

Was just trying to get a screenshot of the new UI in action. 

While it does get "stuck", pressing esc allows you to escape.

Just an UI glitch that I found amusing...
