  2. Click the green circle to maximize
  3. Move the cursor to the top of the screen
  4. Observe that window decoration doesn't appear
  5. Press escape key

What is the current behavior?

No window decoration; screen goes black

What is the expected behavior?

Window decoration should appear; should return to desktop.
