Photoshop: CS6 display problem in Dual monitor mode (MacOS driver bug)

When I drag one of my PSD's between my monitors in Photshop CS6 it becomes buggy/scrambled/unviewable on one of them.

I have a 27" mac display (non-thunderbolt) and a 17" macbook pro (early 2011) - and the PSD is scrambling on the macbook display.

It is even to the point where if I have half the PSD open on the 27" and half on the macbook - only the macbook portion is scrambled.

That's an OpenGL driver glitch.

Which OS version are you running?
We'll have to see if we can reproduce it and document the problem for Apple.

Apple did fix some display driver bugs in 10.7.4 (many for laptops) - you might want to install that update and try again.

And sometimes disabling automatic graphics switching can help (use the good GPU all the time instead of switching to the low power one randomly).

I'm running 10.7.4 and this is still an issue, even when un-checking graphics switching.

Hmm, other people aren't seeing that problem. My first guess would be that you have a bad graphics card or VRAM in your system.

I'm having the exact same issue...frequently. The only fix is to restart the computer. Restarting Ps does not resolve the issue.

The behavior is the same on 10.7.x and 10.8 for me.

I have run across something like this too. I am running an MBP 17" Oct 2011 edition on Lion 10.7.4. 2nd monitor is a 27" iMac using Target Display Mode and a Thunderbolt cable. Bridge is fine in the 2nd monitor; overall frame of the PS CS6 window is fine on the 2nd monitor, but the document area is messed up. It often comes up garbled, and if I zoom in/out with CMD+/- the rulers and zoom indicator update, but the document is unchanged. When I split the window across monitors, the portion on the MBP is fine, the portion on the iMac 2nd display is garbled.

Interestingly, when I exited PS CS6 and came back in, it seemed to work fine. It may be a problem caused when the 2nd monitor is activated after PS is already running?

Photoshop itself should deal with that just fine (it detects the display changes and updates things accordingly).
But some of the system drivers might not be handling it well.

Hi Chris. Yeah, it didn't make sense that it would be related to monitor change, but that was the only thing that had changed when the problem went away. Subsequent to my restarting PS CS6, the problem has not re-occured. I'll post an update if it recurs.

I'm also having this problem 100% of the time. I'm running 10.8.2 on a brand new macbook air that has all its specs maxed out. The monitor is a Dell 2407 24" model that I'm connecting to via DVI through a thunderbolt-to-dvi adapter.

I have this problem as well. running OS 10.7.5 on a 17" macbook pro and have a cinema display as the second monitor. seems like the monitor won't update anything in on the canvas. However, all other interface elements work just fine.

Please let Apple know about this and that you consider it important to get fixed.
We haven't been able to reproduce the problem ourselves, but have asked the GPU vendor to investigate.

interestingly I now have a new macbook pro and I STILL get the same problem -

It occurs infrequently - but the garbled image only occurs on the macbook display - not the cinema display itself - so the secondary display.

Which kind of - for me - rules out the physical connection idea because it only happens when my macbook pro is in dual-monitor mode, and not when I am using it alone.

My guess is it is something to do with dual-monitor mode - and the software re-drawing the image on the new monitor (when you drag it over).

just the facts:

It transcends computers - as I am now on a completely different machine
I am using the same 27" non-thunderbolt apple display
it only occurs sporadically
it only occurs on the secondary monitor (as defined by OSX)
It has happened on 10.7, and now 10.82

My guess is that it has to do with dual displays and buffering, and is probably restricted to a few GPU models and OS versions.

We won't know more until we can reproduce the problem here.

I recently encountered a user that had this same issue. Recommended her to try rebooting her macbook with the extra display attached when restarting and she is now able to use both displays with Photoshop.

Try setting Preferences>Performance... [Advanced Settings...] and set Drawing Mode to "Basic" and restart Photoshop. Does the problem go away?

Well this same user came to work and experienced the problem again. This time she rebooted with the displays attached and it worked perfectly again. So everyone should try rebooting with displays attached. It could be an issue with the program not adapting to hardware changes well. -kt

Did you try the solution I posted above for adjusting the Drawing Mode setting?

You should absolutely try what Jeffrey Tranberry suggested. It worked for me.

I'm having this same issue with Macbook Pro Retina, CS CC, 10.8.2 and two Dell Displays. Restarting each time is not a sufficient solution.

Please see the previous responses, and let Apple know about the problem so they can get it fixed in their driver code.

Brand new 15" MBP with Retina (completely maxed out) and a Cinema Display... running 10.8.5 and CS6 (and CC). I get a black screen about 75% of the time.
