Dolphin ignores directory group permissions

I don’t know if it’s a bug in dolphin 24.02.1 or I’ve forgotten to configure something that has changed, but I can’t create a new item or paste on a directory that belongs to another user but I have group permissions for writing.
I can create a new directory or copy any file from terminal but not with dolphin.

Please, tell me if I’ve forgot something new in this version or I should report it as a bug.

Thanks.

Yea, there is/was a bug about group permissions not being taken into account correctly. See 483436 – Incorrect display of file icons (thumbnails).

This has already been fixed in the KIO framework. The upcoming framework 6.2 version is expected to not show this bug anymore.
