Performance on big boards heavily degraded after Update - Maybe Vue Issue?

[DrakeHamString]

Describe the bug
After updating my Nextcloud AIO instance to 33.0.6 and Deck to 1.17.4, our big shared Desk boards became unresponsive and every action needs some time to load. Those got a big performance impact

To Reproduce
Steps to reproduce the behavior:

1. Go to a board with many cards and/or many users (e.g. more than 50 cards)
2. navigate / scroll / edit cards - you already see the effect

Expected behavior
Snappy navigation

• Do you observe any slow request in Network tab?
• Could you please share the browser console log?
• Have you tried on other browser?
• What is the version of NC and Deck before upgrade?
