Thumbnail/Quick Preview/Export have strange grey overlay
I have a library with a single project and a series of photos in it. Most photos have a crop, white balance, exposure, sharpen and curve global adjustments, as well as areas with definition brush strokes and dodge brush strokes. The dodge brush was used to make the "almost white" background around product in the shot completely white.
The thumbnails display a light grey (around 250;250;250 RGB, although it varies a bit) blotchy overlay in the areas of the image that are expected to be white. When I click on a thumbnail to bring up the larger image into view, for the first few seconds, while the "loading" spinner is visible on top, the grey overlay can also be seen on the enlarged image. After loading is finished, it disappears. If I turn on the Quick Preview mode, the grey overlay persists and does not go away. Images that I have viewed enlarged with Quick Preview turned off continue to display correctly when I come back to them after looking at other images, as if they are cached in memory. After I view a few dozen images, though, these correct versions seem to be evicted from cache, and I get the grey overlay during the "loading" period again.
The grey overlay does not correspond one-to-one with the area where brush strokes have been applied.
The scariest part of it all is that when I try to export versions, they are exported with the grey overlay intact.
I have tried rebuilding thumbnails, reprocessing masters, repairing permissions, repairing the database. The problem persists. I have tried disabling the dodge adjustment but unchecking it and then checking it again. The problem persists. I have tried removing the dodge adjustment and then brushing it on from scratch. The problem persists.
Out of ideas now. Please help. I would love to attach screenshots, but don't see an option to do so.
