Operating System & Version

macOS 15.5

Description

When navigating pages in a library, duration labels on file thumbnails persist after changing pages. Possibly the same issue as or related to #965.

Expected Behavior

Duration labels should only show for applicable file types (i.e. audio, video).

Steps to Reproduce

1. Open a TagStudio library that contains a mix of audio/video and non-audio/video files across multiple pages
2. Navigate to a new page and observe how the duration labels from the previous page are still present on the same grid locations, regardless of file type
