If I understand correctly you are wiggling the cursor to find it, and after a doing it a few times your screen seems to flicker or flash. I would use these steps about troubleshooting graphical issues with a built in display on your Mac:

Reset the system
You can reset the Mac's parameter RAM and SMC.
- Start up in Safe Mode.
- From the Apple () menu, choose System Preferences.
- Choose Displays from the View menu to open the preferences pane.
- Select any resolution and refresh rate that your display supports.
- Restart your computer.
Thank you for using Apple Support Communities.
