Graphics/artifacting issues with new mid-2014 15" MacBookPro Retina

Question

I'm having graphics issues with my new 15" mid-2014 2.8 MacBookPro Retina.  It came with Yosemite.  I keep get glitchy
artifacting when using Premiere Pro and After Effects (CC 2014), obviously, but then even just while using Finder when AE and PP are closed.
I've read about it with earlier models, but nothing about the new ones.
I turned off the Automatic Graphics Switching in Energy Saver and just updated my CUDA NVIDIA driver.  It's still a problem.  Any ideas on what to do next?
Thanks in advance.

Answer 1

Remove CUDA and see whether there's an improvement.
To remove CUDA, triple-click anywhere in the first line below on this page to select it:
/Library/Frameworks/CUDA.framework
/Library/LaunchAgents/com.nvidia.CUDASoftwareUpdate.plist
/Library/PreferencePanes/CUDA Preferences.prefPane
/System/Library/Extensions/CUDA.kext
/System/Library/StartupItems/CUDA
/usr/local/cuda
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Continue with the remaining lines. Some of the items may be absent, in which case you'll get a message that the file couldn't be found. After moving all the above items to the Trash, restart the computer and empty the Trash. Don't try to empty the Trash until you have restarted.
If you haven't already done so, back up all data before making any changes.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
