Summary:
I'm using a hot corner to put my display to sleep and at the same time to require authentication when I press any buttons. Sometimes waking up from sleep the login screen doesn't immediately show up but only shows a black screen. The mouse pointer is also visible, but I'm not able to log in. The same also happens sometimes when closing my machine and waking it up.

Steps to Reproduce:
1. Move cursor to hot corner to put display to sleep or close notebook
2. Press any key or open notebook
3. See black screen and not the login dialog

Expected Results:
Be able to immediately login

Actual Results:
Black screen with mouse pointer visible and movable. No login dialog for 5-10 seconds. 

Version:
OS X 10.9.3 (13D65)

Configuration:
13" rMBP, Late 2013, Core i7, 512 GB SSD, 16 GB RAM

Uploaded several sysdiagnoses after Apple's request. Still an occasional issue through OS X 10.10.3 (14D72i).
