This issue caused us no end of problems as we have quite a lot of data controls, specifically the combobox. Managed to get around the issue by downloading the source code and commenting out the text as previously described in the MetroComboBox resource dictionary

                    <Border x:Name="ValidationErrorElement" BorderBrush="{DynamicResource ControlsValidationBrush}" BorderThickness="1" Visibility="Collapsed">
                        <ToolTipService.ToolTip>
