    Layered PSD files getting corrupted when applying a gaussian blur.

    sinnottbrossupport

      A file is created then three layers to keep simple a red square is created using the marquee tool then filled with a colour this is repeated on the next layer with a different colour then the third layer is completely filled with another colour.

       

      The first two layers are selected and scaled then made transparent.

       

      Finally the layer in between layer 3 and layer 1 is selected and a gaussian blur is applied this is when the corruption occurs

       

      Files are being created using Adobe Photoshop CS6 version v13.0.6 and OSX v10.9.3 on Mac Pro with the below specs:

      After file is corrupted Photoshop has to be closed and re-opened because subsequent files that are opened are corrupted.


      This has been reported in CS5 and CS5.5 extensively but not so much in CS6.

          You can reproduce this on demand with a particular document as input?

           

          Adobe might like to have a copy of a PSD saved from that document (assuming loading it then running Gaussian Blur reproduces the problem).  Can you post it online somewhere, or give explicit instructions on exactly how to create it?

            Below is the steps that where used to create the corruption in the files.

             

             

             

            Gausian Blur corruption in Photoshop

             

             

            Step 1. Create document with 3 layers + Background.

            Step 2. Layer 3 - Create a box (Red)

            Step 3. Layer 2 - Create a box (Blue)

            Step 4. Layer 1 – Fill layer (Yellow)

            Step 5. Select layer 3 & 2 & scale down & press
            return

            Step 6. Change opacity of layer 1 & 2 to 25%

            Step 7. Go to layer 2 and select Gaussian Blur filter

            Please Note that the blue & Red Box Have changed
            colour.

            As I Zoom in and out the corruption gets worse.

             

             

            Sometimes this corruption dose’nt show up until you have
            saved & reopened the file
            .

              This problem could be specific to your particular system or platform, or something that you didn't mention (like the precise size of the images,how you're filling your rectangles, etc.).

               

              I just ran through it several times with small and large images, trying to match what you showed above.  Every time my display looks normal at the point of Gaussian Blur (where yours has lost its color), and the operation completes normally and leaves the image uncorrupted.  Hopefully someone with a Mac will try the same steps.
