I had the same problem. And I solved it as below:
AFTER EVERYTHING, MEAN THAT THE EMULATOR HAS TWO DIFFERENT WINDOWS THAT ARE ACCEPTED TO OTHER OTHERS.
- Right-click the top panel of the emulator and install it as always on top
- Right-click the emulator icon on the dash and select "Emulator" this time using the ALT + SPACE shortcut to open the context menu and always select again from the top.
AND THIS!
NOTE: EVERY TIME YOU MINIMIZE THE EMULATORY WINDOW, PERFORM STEPS ABOVE.
