Before doing a clean reinstall I tried just reinstalling Premiere Pro CS6. So now I have both Premiere Pro CC and CS6.
CS6 works fine with XDCAM EX footage but CC still shows the glitches and green frames/screens.

If you are in a rush and need to finish a project before doing a clean install, you can re install CS6 following these steps:

Open creative cloud manager.
Go to apps then click more information below Premiere Pro CC.
In your browser you will see a page with info about Premiere CC.
Under “This Version” there is a pull down menu where you can choose CC or CS6.
Choose CS6 and now the download button says “Download Adobe Premiere CS6”

I will now do a clean install of everything and will report again.
