When I edit a photo, I hit the space bar to trigger the "save changes" dialog, and after I confirm, there is a short time to wait while the file is saved and then until the next photo loads. It seems like the application can pre-load the next photo, making it ready to display before you even get to confirm that you want to save/write the first file. And after the next file is displayed, then save/write the previous file. Reproducible: Always Steps to Reproduce: 1. See details for description 2. 3.
