Red wheel keeps turning, blocks display of new items

[byeight]

Steps to reproduce

1. Fresh install of 2.1.27.8 or upgrade from 2.1.27.7 to 2.1.27.8
2. Add items to a folder, at least 20 to 30
3. Click on the folder

Expected behaviour

Normal behaviour

Actual behaviour

At some point, 1 Teampass installation has this problem as of more than 24 items in 1 folder, another installation with more than 28. The difference in number could be explained because somehow the folders are also counted. But the problem is that next to the search window a red wheel keeps turning and never goes away.
When trying to add a new item in this folder it does not display this new item. Only after deleting a few items the red icon disappears and the newly added items suddenly appear.
So this problem only occurs upward of a certain number of items in a folder.

Would it be possible for you to check the error log.
It must contain errors when you have this spining cog staying visible.

Hi Nils,

This is the Apache errorlog when the spinning cog is visible. Also when viewing a folder with 60 or more items only about 28 will be visible with the red cog spinning. This is something new with the latest release.
