Old artwork of previously deleted programs still appears on the media library covers

[phoesky 0]

Problem: After updating Emby to 4.9.5.0, old cover pictures of long-deleted content keep displaying on covers throughout all media libraries. Regular rescanning cannot fix this display issue.

Emby Server: Official Synology Package 4.9.5.0

Device: Synology DS423+

DSM: 7.2.1-69057 Update 11 (No DSM upgrades planned; new DSM versions remove native server-side hardware decoding)

I have two screenshots for reference. This library is only provided as an example, and this bug affects all of my media libraries, not just this one.

Screenshot 1 shows the combined 4-in-1 cover thumbnail displayed on this regular library page.

Screenshot 2 shows the actual current content inside this media library.

 

Issue details:

The 2nd and 4th poster thumbnails on this combined cover belong to items that I permanently removed from the library over a year ago, yet they still remain in the composite cover preview.

The 1st and 3rd poster thumbnails are old custom artwork I manually replaced a long time ago. My newly updated custom covers never take effect on this merged four-panel cover preview, while outdated cached thumbnails persist permanently.

This abnormal cache refresh failure for library collage covers started to happen after I upgraded my Emby Server to version 4.9.5.0. Could you help check the global cache mechanism for these combined library artwork previews and provide a solution to fully clear stale cached images? Thanks a lot.

Hi, try using the image editor to delete the existing image. Then run a library scan and that should create a new one.
