Current behavior
If you have a LayoutTransformControl like so:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid x:Name="Grid">
<controls:LayoutTransformControl>
<controls:LayoutTransformControl.Transform>
<TransformGroup>
<RotateTransform Angle="25" />
<ScaleTransform ScaleX="4.5"
ScaleY="1" />
<SkewTransform AngleX="0"
AngleY="0" />
</TransformGroup>
</controls:LayoutTransformControl.Transform>
<Border Background="#FF333333"
BorderBrush="Red"
BorderThickness="5">
<Grid>
<TextBlock Padding="10" Foreground="White" Text="This is a test message." />
</Grid>
</Border>
</controls:LayoutTransformControl>
</Grid>
</Page>
You get one result:
But when Grid is a UniformGrid instead, you get a different result:
Expected behavior
As per WPF, these should result in the same behavior.
Minimal reproduction of the problem with instructions
Use provided XAML in sample app for LayoutTransformControl.
Other Info
I have confirmed this behavior was there before change #2149 as well, so that change did not introduce this behavior.
I'm not sure if this is an issue with the UniformGrid or the LayoutTransformControl or the interaction between their two layout algorithms. Since it does work with Grid and UniformGrid does inherit now from Grid it is a bit odd, so leads me to believe it may be the former.
