Title: P'shop layers with unexpected transparency
Post by: CBarrett on March 20, 2009, 07:30:27 pm

Ok.  I'm freaking out.  Here's the deal.  I selected a small section of my background layer with the marquee, copied it and pasted it (creating a new layer).  The layer is set to normal with 100% opacity and fill.  Yet, it is slightly transparent.  When I move it around I can see elements of the background layer behind it.

CS 4 Mac.

Any thoughts?

Thanks,
Chris

Well, first the obvious: does the background layer have transparency?  I am not questioning if the background opacity and fill is at 100%, I am asking if the background layer has transparency.  You could check this by creating a solid color layer and then duplicating the background layer and moving it over the dupe.  Does color show through?

Second obvious question: did you perhaps activate a blend mode by accident?  Some blend modes like Lighten and Darken could give the impression of partial transparency.

If those are not the problems, I would maybe start thinking that you may have one of those weird OpenGL/video card glitches.  Try turning off the OpenGL Drawing in Edit>Preferences>Performance.  If that fixes it but you want to try to keep the OpenGL functionality, check to see if there is an updated driver for your video card.  That might help.
