Description Akseli Lahtinen 2023-05-01 19:02:18 UTC 
SUMMARY
If a playlist contains +5000 files, and one toggles the "Party mode" Elisa freezes completely.
I assume this is because it tries to load *all* album covers, instead only the ones visible to user.


STEPS TO REPRODUCE
1. Have a huge music collection
2. Add all tracks from that to a playlist
3. After it's done loading, open party mode

OBSERVED RESULT
Elisa freezes completely

EXPECTED RESULT
Elisa should not freeze. It can be a bit slow but not freeze.

I am also experiencing this issue with Elisa 23.04.1, and downgrading to Elisa 22.12.3 makes the issue go away.

Update to this

The actual list of tracks does not freeze. It's the playlist that causes the freeze. It seems playlist view is trying to load all album arts the moment the slider is moved somewhere?
