MainStage: Controls sometimes flash black

Issue or symptom

Some onscreen controls may flash black sporadically while playing.

Solution

This sometimes happens with the nVidia 5200 graphics card while in Performance or Full Screen mode. It is more likely to happen with display resolution settings of 1600 x 1200 or higher. It may help to lower the display resolution for the computer:

1. Choose Apple menu > System Preferences.
2. Choose View > Displays.
3. Click the "Display" tab in the Displays window.
4. Select a lower resolution setting for your display.
