Summary:
The display goes into power save mode repeatedly when using mavericks. After about  1 second, the display turns back on.

Steps to Reproduce:
1. Have Mavericks (10.9, 10.9.1, or 10.9.2).  The issue has been present in every version, but has become unbearably frequent in 10.9.2.  The issue DID NOT EXIST in Snow Leopard, Lion, or Mountain Lion.
2. Mouse over dock, and move mouse over different apps.  Keeping the mouse moving will keep the display blank for an indefinite period of time.  Disabling animations reduces the frequency, but does not eliminate it.  This is not the only way to reproduce (clicking on files on the desktop works) but is the most reliable.

Expected Results:
I expect both displays to continue to function.

Actual Results:
My 2nd display enters power save mode.

Version:
OSX 10.9.1

Notes:


Configuration:
iMac - 2.8 GHz Intel Core 2 Duo
4GB 667 Mhz DDR2 SDRAM
Serial: QP8130QZX8A
Asus MW221 monitor - DVI connection with Apple adapter
