I recently upgraded Photoshop from CS4 to CS5 and all is good and well. Except that my guides that I drag out from the ruler is displayed with 2 pixels (screen pixels) all the time instead of 1 pixel as i should be.
No matter what zoom level I'm at, the guideline is 2 px thick, which is bizarre. I can't imagine that anyone would want this, so I guess it's not a setting?
Anyone else having this strange issue?
Sounds strange – could you post a screenshot?
Other than that are you fully updated with regard to Photoshop and OS and have you performed the usual trouble-shooting routines (trashing prefs, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?
YES! That did the trick! When I turned Open GL off it displayed the guides correctly! Then I tried activating Open GL, but unchecked the second checkbox under the advanced setting for Open GL, and that did it.
The question is, what is the point with the setting I switched off?
»Anti-alias Guides and Paths«?
I suppose for vertical and horizontal Guides Anti-Aliasing is not especially useful but for Paths which may bend whatever way that may provide for better previews – or not … I did not test it.

If you enabled “advanced features” from catalyst control center, like, Smoothvision HD Anti-Aliasing, just to be sure “Anti-alias Guides and Paths” trick will not work. Disable “Smoothvision HD Anti-Aliasing” from catalyst control center then un-check “Anti-alias Guides and Paths”.
