After rebooting, I tried WD2 again. This time worked fine, but after changing settings, going back to the menu, reloading a game, it flickered black once (bad sign). Game ran, but after quitting the game and being back on my desktop, the top of my screen would flicker. These drivers seem to have some issues, at the very least with the 390, and based on reports here most likely related to voltage. Edit: Tried it again, issue appeared once more. It happens every time I quit WD2. I reset my drivers with Radeonmod to make the problem go away. Top of the screen keeps flickering otherwise.
