FileChooser display bug

README.md

Hi,

Currently a user is experiencing the following issue with software I have written using kivy.

main.kv

<SaveDialog>:
        text_input: text_input
        filechooser: filechooser
        BoxLayout:
                size: root.size
                pos: root.pos
                orientation: "vertical"

                BoxLayout:
                        size_hint_y: None
                        height: '35dp'

                        ToggleButton:
                                text: "Icon"
                                state: "down"
                                group: "filechooser"
                                on_release: filechooser.view_mode = 'icon'

                        ToggleButton:
                                text: "List"
                                group: "filechooser"
                                on_release: filechooser.view_mode = 'list'

                FileChooser:
                        id: filechooser
                        path: "~"
                        on_selection: text_input.text = self.selection and self.selection[0] or ""
                        FileChooserIconLayout
                        FileChooserListLayout

                TextInput:
                        id: text_input
                        size_hint_y: None
                        height: '24dp'
                        multiline: False

                BoxLayout:
                        size_hint_y: None
                        height: '35dp'
                        Button:
                                text: "Cancel"
                                on_release: root.cancel( )

                        Button:
                                text: "Save"
                                on_release: root.save( filechooser.path, text_input.text )

main.py

def show_dialog( ):
  content = SaveDialog( save = self.save, cancel = self.dismiss_popup )
  content.filechooser.path = os.path.expanduser( "~" )
  self._popup = Popup( title = "Save File", content = content, size_hint = ( 0.9, 0.9 ) )
  self._popup.open( )
