I like to have some folders on the 2nd-lowest zoom level (black folder icons), and this usually restores when I log out and log back in with a dolphin window open. However, sometimes when I log back in, the zoom level resets to big blue folder icons and I have to zoom back out again.

It may be relevant that they are in the Details View mode.
I'm not able to reproduce this in Dolphin 16.12.3. If you still see this after upgrading to a newer version, please comment.
