Description Chris Warren 2024-12-07 13:12:09 UTC 
SUMMARY

With Previews enabled, Dolphin doesn't show the preview for a file that has been renamed until the view is manually refreshed

STEPS TO REPRODUCE
1. Have Previews enabled
2. Navigate to a directory where there's a file you'd like to rename that currently has a content preview as its icon
3. Rename the file that is showing a preview of the file

OBSERVED RESULT

The icon associated with the file changes from a content preview to a generic media type icon as though I either had previews turned off or there was an issue generating a preview for the new file.

This happens in both local and remote (NFS via a mountpoint) operations. It also happens regardless of whether I hit F2 to rename or right click -> Rename.

If I reload the file view in some way (either F5 or navigate out and then back into the directory), the preview is regenerated under that new filename, so that is a workaround.

EXPECTED RESULT
The preview associated with the old filename is now associated with the new filename without needing to reload anything

Comment 1 Chris Warren 2024-12-07 13:49:19 UTC 
One additional nuance that I just noticed that may only be tangential to the issue I reported -- previews for video files do end up regenerating without reloading the view if I happen to mouse over the icon. 

It looks like that may be related to the fact that videos show different frames in the preview. Images don't have the same behavior on hover, at least non-animated images.

I'm not able to reproduce this on Dolphin 24.08.3 or built from today's git-master
After I rename a file, the preview briefly changes to a generic icon, but then switches back to the correct file preview

I'll keep this open in case someone else is able to reproduce

I can reproduce this, it happens with jpg and png files at least. Have to manually refresh or change folders for the preview to pop back up.
