Clicking back to the newly made proofing copy, it then shows normal behaviour. Clicking onto a different photo in Filmstrip restores normal behaviour on that image. Exiting crop tool using Close button in that panel, all other adjustments show unavailable (greyed out) and main window continues to show featureless grey. Except after creating the new proofing virtual copy, the main window in Develop shows completely mid grey - no picture, no ctop interface. Use graphics acceleration 'Auto': same steps. Resulting proofing virtual copy rhen displays correctly for adjusting the crop, When prompted, click on 'Create Proof Copy'. Use graphics acceleration 'Off': turn on Soft Proofing. GPU is NVidia GeForce RTX 2060, driver 31.

And the larger central section is just the main window - or similar words to that effect.Īh, OK - I had missed the soft-proofing aspect and I can also reproduce. To help you explain in any followup or other queries: the narrow section along the bottom of the screen showing small versions of your images, is usually called the 'Filmstrip'. Perhaps then updating the driver software for your particular graphics card might improve its behaviour, when later re-enabled. And see whether the cropping preview goes back to normal. I would also suggest then closing and re-starting LrClassic. To check this, you can set 'Use Graphics Processor' to OFF in the Performance tab of Lightroom's Preferences. The graphics acceleration can give a much more responsive experience (when it works well), but can cause weird display issues (when it turns out to be incompatible in some way). Using the conventional processor is reliable and well tested but not the quickest. That is where the fast electronics within the graphics card get called in to do some of the display calculations, which would otherwise be left to be done more conventionally by the computer's main processor. Often when things don't appear correctly on screen as people edit, this has to do with graphics acceleration.
