Question: videos playing turn green

Upgraded Safari to Version 11.0.1 (13604.3.5) now when I play a video on Quicktime player the video turns to green, you can still see the video but it's like the green is now maxed out. How do I correct this.

Only when using Quicktime player or iTunes, videos played on the browser are fine the other problem I've noticed after I upgraded is, when I turn on or wake my system I have to adjust the Underscan not the display setting. The display turns on too larger for the upper control bar to be seen. None of these issues occurred prior to the last upgrade system was running great. Hope this helps . Thanks.
