I occasionally have trouble when cropping a photo.
Everything seems OK but occasionally the data that has been cropped out remains associated with the image albeit distorted. [I can post a screen shot if you want.]
This usually only shows up when using 3rd party filters.
Topaz ReMask is one that shows this data and will actually use it as if it is still a valid part of the image.
I have tried reloading the image; I have tried rebooting the computer. None of that helps.
The only thing that works is to use the crop tool to re-crop the image [at the same borders]. The extraneous, distorted data is then permanently removed.
Hardware diagnostics show no problems with my computer including RAM.
Once I spot it, it's a 15 second fix so it's not a real big deal. I just wonder about it and wonder if anybody else has seen this.
Any ideas about this? Is it a PS bug?
