PM6 Window 10
I have noticed this on my desktop and laptop:
Sometimes if I color tag images, view only them, then F1 to view all, some images will not be there until after I do a / (rescan). Both some color tagged images and some not-tagged.
Maybe related, maybe not, there have been a few times when I open a contact sheet and start scrolling down, only to later find images at the top of the contact sheet that were not there when I started. I have seen this on freshly ingested images (but the card had finished copying) and directories I have open dozens of times. Maybe it is reading the cache version then adding in things the cache did not know about after the fact?
