Weird pixelation / lines / grid when zoomed out on Photoshop CS4

I have the problem mentioned here: http://forums.adobe.com/message/2824585
I have CS4 Extended (11.0.2) installed on my computer. The program has worked well for years until I upgraded from Windows 7 to Windows 8. I freshly installed photoshop and now, when I open up a picture and am zoomed out at all, a weird pixelated pattern occurs. Here's a screen shot of the problem when I'm zoomed out on a family snapshot:
When I zoom in to 196% or more, the grid problem leaves. If I'm zoomed at 195% or lower, then there is this severe grid problem.
I've tried disabling gridlines and disabling OpenGL, but nothing has helped. Any ideas would be greatly appreciated.
Update: If anyone else has this problem, I figured it out. I had to disable OpenGL and restart photoshop for it to work. Now it works like it always has. I imagine new drivers from ATI might fix this, but they don't exist for my graphics card for Windows 8.
