The header storage bar (microSD/System) used ThemeEntryID_BACKGROUND and ThemeEntryID_TEXT_INFO. When a theme sets background to an image path, no colour is set for that entry, so the bar got an unset/default colour (often white) and looked wrong on dark themes. Use PROGRESSBAR and PROGRESSBAR_BACKGROUND for the bar so it always uses theme colours that are defined as colours, not images.
