防止WPF中閃爍的按鈕

我創建了一個WPF應用程序。這必須有一個紅色的主題。所以我將每種顏色都設置爲紅色，但問題是窗口內的所有按鈕在窗口打開時開始閃爍。有趣的是他們同時開始，但過了一段時間他們開始分歧。當表單失去焦點時，它們都停止閃爍。單擊按鈕時，只有該按鈕保持閃爍。但是當一個「不按鈕」控件獲得焦點時，它們都會再次開始閃爍。防止WPF中閃爍的按鈕

我發現它可能不得不用Focusable屬性做一些事情，但改變它並不會改變任何東西。我還找到了一種覆蓋默認樣式的方法，但這並不能解決問題以太。 Source

這是我的XAML代碼：

    <Label x:Name="lTitle" Content="Server Settings" HorizontalAlignment="Center" Margin="182,0,0,166" VerticalAlignment="Center" Width="118" Foreground="#FFFF9999" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="16" FontWeight="Bold" Height="34"/>

我沒有做任何編程還，所以我.CS文件是空的。
