Widgets acting weirdly

Just have this weird problem whenever I add any widgets in sidebar/footer, the widget field auto loads up and I need to refresh my page to write the widget title. Perhaps I am not expressing myself clearly, screenshot added. If I add any widget it looks like this(recent comment widget) and I literally have to refresh every time I add widget to set the widget parameters. any help would be appreciated.

changing to default themes will resolve this issue(that means it’s a theme specific problem), disabling all plugins don’t help.
