Hi there, I recently upgraded from Photoshop CS3 to CS4 and have been running into an extremely irritating bug with the OpenGL acceleration in Photoshop.
When I use Exposé or Spaces, say to grab some filler text from the ol’ Lorem Ipsum generator, and switch back into Photoshop, the image intermittently ceases to redraw correctly.
For example, if I select some text, delete it and type some new text in, the changes don’t appear until after I’ve typed the text, applied the changes, then switched tools. Or say I paint something with the brush tool, and then undo the change. The History panel will change, but the image appears *exactly* the same, until I either switch tool, move a layer with the move tool, paint something else with a brush or anything else that seems to "force" a redraw.
The problem goes away (on my 9400M at least, I haven’t tested this "solution" on the 9600) if I open the Logout window, or click on a window in the background to give it focus. This does not occur if I disable OpenGL acceleration, but software mode looks pretty ugly, and the smart guides (which I love), run absolutely horribly.
I have a Macbook Pro one of the new unibody ones, with a 9400M and a 9600M GT. 2gb RAM, Core 2 Duo 2.4ghz, etc. I’m using Leopard 10.5.6 with everything up to date.
This problem is intermittent, seemingly happening less frequently when using a 9400M as opposed to the discrete 9600M GT. It happens on both the laptop’s screen, and an external monitor.
Has anybody else hit the same issue, and found a more permanent workaround? Any beta drivers I should know about?
Thanks in advance.
