Lately I have been having issues with the screen in my VM running under Fusion flickering. This is particularly annoying when working in Visio and trying to draw up a diagram. It is not good for the eyes 🙂 The below screenshot shows the issue I have been experiencing: To stop the flicker enter the VM settings and turn off 3D Acceleration under the Display configuration.  You will need to Power off the VM before you can make this change.  Once the VM is powered on the screen will no longer flicker, therefore saving your eyesight 🙂
