We implemented a fix in a new version of the Dropbox desktop application that ensures consistent folder icons and file/folder permissions for items in the Dropbox folder.
This means that you may see that custom folder icons are removed. Additionally, if you have files or folders in the Dropbox folder with custom permissions (such as custom POSIX permissions or BSD flags), these may be removed to ensure the file syncs to other devices without any issues."
