If present windows effect is active it is not possible to lock the screen.

Reproducible: Always

Steps to Reproduce:
1. Enable Present windows under settings -> desktop effects
2. Hit CTRL+F9 or go upper left with the mouse cursor if you have this effect's sfortcut enabled
3. Try to lock the screen using CTRL+ALT+L or suspending the computer
Actual Results:  
Screen lock doesn't work if you suspended the computer when resumed you won't be asked for the password.

Expected Results:  
The effect is cancelled and the lock correctly applied.

I think this is kinda a security issue, even if might be *low* risk.
