Why are embedded videos suddenly playing in black and white, sometimes with a green tinge?

@glacial Different Q.

Update maybe corrupt. Try reloading update and then if that doesn’t work delete Adobe (all of it) and start all over again with fresh Adobe download.

You can try Chrome since it uses it uses its own version of Flash. I’m not saying you should switch to Chrome. I wouldn’t use a browser made by a advertising company. At least try it and see if things work. If it does work then you can pretty safely say your instal of Flash went wonkey.
