I have noticed a bug in Mission Control on macOS Sierra (10.12.2).
Here's a GIF to reproduce the bug:
It happens when I try to open an app from the Dock, while I'm showing the Desktop: the app doesn't open, windows come back in place, then if I toggle Mission Control, the app I clicked before opens (or get in front if already opened).
Step by step, as shown in GIF:
Click on any app in the Dock
App won't open, windows come back in place instead
Open Mission control
Exit Mission control: previously clicked app opens
Is anyone experiencing the same?
