问题
I hope that it is clear enough in the image, I have a triangle with shadow effect that doesn't look so good, seems to be broken somehow. Any help will be greatly appreciated.
(Update: the rectangle and the path have to be separated)
XAML:
<Grid Height="50" Width="60" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Rectangle Grid.Column="1" Stroke="Black" Fill="White">
<Rectangle.Effect>
<DropShadowEffect Opacity="0.5" ShadowDepth="4" BlurRadius="10" />
</Rectangle.Effect>
</Rectangle>
<Path Fill="White" Stretch="Fill" Stroke="Black" HorizontalAlignment="Left" Margin="0,15,-1,15"
Data="M44.386378,164.8791 L22.983157,171.42119 44.713478,176.58567" Width="23.167">
<Path.Effect>
<DropShadowEffect BlurRadius="10" Opacity="0.5" ShadowDepth="4" />
</Path.Effect>
</Path>
</Grid>
</Grid>

On your triangle:
- Remove the Margin
- Set the Path height explicitly ("22" is pretty close what you have there).
That should prevent the triangle's shadow from being clipped.
Here's the xaml for that:
<Grid Height="50" Width="60" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Rectangle Grid.Column="1" Stroke="Black" Fill="White" >
<Rectangle.Effect>
<DropShadowEffect Opacity="0.5" ShadowDepth="4" BlurRadius="10" />
</Rectangle.Effect>
</Rectangle>
<Path Fill="White" Stretch="Fill" Stroke="Black" HorizontalAlignment="Left"
Data="M44.386378,164.8791 L22.983157,171.42119 44.713478,176.58567" Width="23.167" Height="22">
<Path.Effect>
<DropShadowEffect BlurRadius="10" Opacity="0.5" ShadowDepth="4" />
</Path.Effect>
</Path>
</Grid>

The problem is you have two separate elements each with a drop shadow. You cannot expect their shadows to join up nicely, the 'blur' is applied separately to each element. Try combining your rectangle and triangle into a single path. e.g.
<Path Fill="White" Stretch="Fill" Stroke="Black" HorizontalAlignment="Left" Margin="0,15,-1,15"
Data="M 0,0 L 100,0 L 100,400 L 0,400 L 0,300 L -50, 200 L 0, 100 L 0,0">
<Path.Effect>
<DropShadowEffect BlurRadius="10" Opacity="0.5" ShadowDepth="4" />
</Path.Effect>
</Path>
