I loaded some images into Lightroom and as Lightroom would render each one, some of them would pixilate, not all. I could go in and in develop they would clear up and I was able to edit and export just fine. Has anyone else ever seen this??? It also does it in Camera Raw, Bridge and Photoshop. I am thinking a card might be going bad.
As a note, loaded another shoot from another card and no issues.
That looks to be some type of hardware corruption.
But first turn off the GPU option on the Performance tab of the LR preferences. If that doesn't fix the problem then those image files are corrupted. The corruption could be caused by a faulty memory card, card reader or USB cable., It could also be because of hard drive or memory faults.
That seems to have helped... just have to see if it stays that way. I had them all cleaned up and then it went though to render them again and they went back to the photos with the issue. It only happen on about 30 photos out of 155. Going to toss this card, still think that has something to do with it.
