    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.
