Hello 👋

Thank you for taking the time to open this issue with the bookmarks app. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and have been maintaining this software the last few years. I currently work for Nextcloud but maintain this app
in my free time, because it is not an official Nextcloud product. My day job at Nextcloud is pretty awesome but sadly leaves me with
less time for side projects like this one than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself. (Also see our Code of Conduct. Really.)

I look forward to working with you on this issue
Cheers 💙

If I click on some tags links on the left hand pane (with a very low number of bookmarks), the view will load. But anything over 4 bookmarks in a tag view will just cause flickering grey bars.

Moved from PHP 8.1 to PHP 8.2 and that seems to have fixed the issue. If someone can confirm that PHP 8.1 with the Bookmarks app doesn't work and PHP 8.2 is required (and that this fix is correct), it would be great. Thanks!

Hello @mbressman
Could you check the nextcloud log file for errors?

If someone can confirm that PHP 8.1 with the Bookmarks app doesn't work

The bookmarks app should work with php 8.1

I cannot reproduce this with the latest version, Nextcloud 31 and PHP 8.1
