Я бы согласился с комментарием Мэтью, но в любом случае ваш ответ - применить собственный стиль без анимации. Вот оригинальный стиль (через отражатель), вы можете удалить / настроить / что угодно:
<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
<Style.Triggers>
<Trigger Property="Orientation" Value="Vertical">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="3" SnapsToDevicePixels="true">
<Border BorderThickness="1,1,1,0" BorderBrush="#BEBEBE" CornerRadius="2">
<Border BorderThickness="1" BorderBrush="#EFEFEF" CornerRadius="1">
<DockPanel Name="PART_Track" Margin="0,0,0,1" LastChildFill="false">
<Decorator Name="PART_Indicator" Dock="Bottom">
<Rectangle LayoutTransform="{RotateTransform Angle=-90}">
<Rectangle.Fill>
<MultiBinding Converter="{theme:ProgressBarBrushConverter}">
<Binding Path="Foreground" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="ActualHeight" ElementName="PART_Indicator" />
<Binding Path="ActualWidth" ElementName="PART_Indicator" />
<Binding Path="ActualHeight" ElementName="PART_Track" />
</MultiBinding>
</Rectangle.Fill>
</Rectangle>
</Decorator>
</DockPanel>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
<Setter Property="Foreground" Value="{StaticResource [0] Ñ}" />
<Setter Property="Background" Value="{DynamicResource {x:Static WindowBrush}}" />

И преобразователь класса:
public class ProgressBarBrushConverter : IMultiValueConverter
{
// Methods
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)

Type type = typeof(double);
if (((((values == null) || (values.Length != 5)) || ((values[0] == null) || (values[1] == null))) || (((values[2] == null) || (values[3] == null)) || ((values[4] == null) || !typeof(Brush).IsAssignableFrom(values[0].GetType())))) || ((!typeof(bool).IsAssignableFrom(values[1].GetType()) || !type.IsAssignableFrom(values[2].GetType())) || (!type.IsAssignableFrom(values[3].GetType()) || !type.IsAssignableFrom(values[4].GetType()))))

{

brush2.Viewport = brush2.Viewbox = new Rect(num9, 0.0, num10 - num9, num2);
TranslateTransform transform = new TranslateTransform();

DoubleAnimationUsingKeyFrames animation = new DoubleAnimationUsingKeyFrames();
animation.Duration = new Duration(TimeSpan.FromMilliseconds(num11));
animation.RepeatBehavior = RepeatBehavior.Forever;
for (int i = 1; i <= num8; i++)
{

animation.KeyFrames.Add(new DiscreteDoubleKeyFrame(num13, KeyTime.Uniform));
}
transform.BeginAnimation(TranslateTransform.XProperty, animation);
brush2.Transform = transform;
while ((x + width) < num10)

}
context.Close();
brush2.Drawing = group;
return brush2;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
