Small graphic gap in ComboBox

[tlostak]

Hello,
as I mentioned earlier I found small graphic bug with ComboBox. I think image and codes will show everything what we need.

This is how It looks:

This is the case with ComboBox and Border.

<Window x:Class="TESTETE.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        TextElement.Foreground="{DynamicResource MaterialDesignBody}"
        TextElement.FontWeight="Regular"
        TextElement.FontSize="13"
        TextOptions.TextFormattingMode="Ideal" 
        TextOptions.TextRenderingMode="Auto"        
        Background="{DynamicResource MaterialDesignPaper}"
        FontFamily="{DynamicResource MaterialDesignFont}" Width="843.816">
    <Grid Background="#FF8B8888">
        <Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="100" Margin="348,42,0,0" VerticalAlignment="Top" Width="184" Background="#FF937979"/>
        <ComboBox x:Name="ComboBoxSort" Margin="0,77,332,0" HorizontalAlignment="Right" Width="114" VerticalAlignment="Top" Background="Transparent">
            <ComboBoxItem IsSelected="True" Content="ID"/>
            <ComboBoxItem Content="Jména"/>
            <ComboBoxItem Content="Zabití"/>
            <ComboBoxItem Content="Bodů"/>
            <ComboBoxItem Content="Umístění"/>
        </ComboBox>
    </Grid>

But bug can be reproduced also by changing grid backgroud color:

<Window x:Class="TESTETE.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        TextElement.Foreground="{DynamicResource MaterialDesignBody}"
        TextElement.FontWeight="Regular"
        TextElement.FontSize="13"
        TextOptions.TextFormattingMode="Ideal" 
        TextOptions.TextRenderingMode="Auto"        
        Background="{DynamicResource MaterialDesignPaper}"
        FontFamily="{DynamicResource MaterialDesignFont}" Width="843.816">
    <Grid>
        <Grid.Background>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="Black" Offset="0"/>
                <GradientStop Color="White" Offset="1"/>
            </LinearGradientBrush>
        </Grid.Background>
        <ComboBox x:Name="ComboBoxSort" Margin="0,77,332,0" HorizontalAlignment="Right" Width="114" VerticalAlignment="Top" Background="Transparent">
            <ComboBoxItem IsSelected="True" Content="ID"/>
            <ComboBoxItem Content="Jména"/>
            <ComboBoxItem Content="Zabití"/>
            <ComboBoxItem Content="Bodů"/>
            <ComboBoxItem Content="Umístění"/>
        </ComboBox>
    </Grid>
</Window>

Thank you :)

I think this issue has been resolved, as I could not reproduce this. Closed.
