VMware Player 6.0.2 (also happens on similar version of VMWare workstation)
Windows 7 x64 guest running on CentOS 6 host
Dell T6510 with Nvidia Quadro K2000 grpahics, driver version 340.46
Dual displays
Sometimes (not consistently) the VMware guest window will start flickering off/on on every movement of the mouse and on each keyboard keystroke. The flicker occurs every time the mouse detects movement, so there are many flickers as the mouse is moved across the screen. The flickering stops when there is no user input. It happens regardless the guest window is full screen or not. It does not matter which of the two displays the guest window is in.
This seems to happen only upon coming back to the desktop after it has been locked and perhaps if the monitors have gone into power-save mode. It's pretty inconsistent: it happens only every few days. Suspending or shutting down the guest and restarting VMware fixes the problem.
