I have the following strange behavior of the dolphin toolbar in Tumbleweed as well as in Leap 42.2 Open toolbar configuration 1) select "hidden files" an place it behind a seperator. 2) give the "hidden files" entry a symbol (symbol chosen does not matter) 3) apply settings The symbol (an the text if that is your setting) is shown in the toolbar However, if the symbol is clicked, the symbol disappears an the text "hidden files" is shown without a symbol. To me that looks like a Bug.
The tool bar button should have an "eye" icon, though. When toggling the action, Dolphin updates the icon, overriding it.
I see. It does have the "eye" icon in the breeze icon theme , but not in other themes. So Oxygen and the other are missing a symbol for this funktion. But on the other hand. If i manually set the symbol to something other than default (the eye) the issue remains. All other symbols than the default are overwritten at first click.
