Green screen with videos

Hi blondiejune,

Thanks for using Apple Support Communities! It looks like you're having an issue watching Facebook videos, and I'd like to do what I can to help.

Have you restarted your Mac since noticing this issue? If not, go ahead and do that, as a restart can resolve unusual issues.

Log out, sleep, restart, or shut down your Mac

Check for any app updates in the Mac App Store. Find Mac software and updates online

Is Facebook the only app this is happening with? If so, you'll want to contact the app developer, and let them know what's happening. How to contact an app developer

Take care!
