Mission Control behaves unpredictably

When switching applications using Mission Control, the application I select moves to the foreground as expected.

However on occasion, it will then immediately jump back into the background. This is very annoying. I closed all my other applications but that did not help. Please see this gif for a demo:

Does anybody have any idea what might be causing this?

Solution 1:

This is a bug of Mission Control, that Apple should fix.

A temporary solution is to:

1. Right click the Terminal icon on the Dock.
2. Click Options.
3. Assigns it to None rather than All Desktops.

This will however not let the app show up on all desktops any more.
