is that with any active window or just one specific app ...

the "grey-out feature" of unity clearly points to either your CPU being
under high load or your disk not being able to deliver data at the
expected speed (I/O issue).

what are your hardware specs (CPU, RAM, does the device have graphics
card needing a binary driver ? )
