调研方向

未指定仓库文件或测试。先使用 MahApps.MetroWindow、MaterialDesignRaisedButton 和 ButtonProgressAssist 运行所提供的 WPF XAML 复现，然后在 4.7.1 版本下运行它，并最小化再还原窗口，以确认内存行为；当泄漏得到解释且报告的场景不再复现时，即表示完成。

Bug explanation

I found a problem, maybe a compatibility issue or a design bug, but I think it can be fixed. My WPF program uses MahApps, (<mah:MetroWindow...), in which I use a button control of MaterialDesignInXamlToolkit, the style of this button control is: MaterialDesignRaisedButton. When I run the program, everything seems to be fine, but immediately after I minimize the form, the memory increases at a rate of 1MB/s, and it won't stop, unless I restore this form that was just minimized, after restoring the memory immediately drop and return to normal levels. I know my question is about coming from two different places, (MahApps and MaterialDesignInXamlToolkit), but if I don't use MahApps(mah:MetroWindow), then, the above problem doesn't exist, everything works fine, also I tried several other Different styles of a similar button, only this style is found so far: MaterialDesignRaisedButton has this problem, the condition that triggers this problem is when the form is minimized.

**xaml code：
<mah:MetroWindow x:Class="WpfApp1.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:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes" xmlns:local="clr-namespace:WpfApp1" mc:Ignorable="d" WindowStartupLocation="CenterScreen" Title="MainWindow" Height="450" Width="800"> <Grid> <StackPanel> <Grid Width="124"> <Button Margin="2,0" materialDesign:ButtonProgressAssist.IsIndeterminate="True" materialDesign:ButtonProgressAssist.IsIndicatorVisible="True" materialDesign:ButtonProgressAssist.Value="-1" Content="Indeterminate" IsEnabled="{Binding DataContext.ControlsEnabled, RelativeSource={RelativeSource FindAncestor, AncestorType=Window}}" Style="{StaticResource MaterialDesignRaisedButton}" /> </Grid> </StackPanel> </Grid> </mah:MetroWindow>

I have captured two pictures. Figure 1 shows that after running the WPF program and minimizing it, the change of memory transmission at this time can be seen to be increasing

Figure 2 shows the memory changes after I restored the WPF program window that I just minimized. You can see that the memory has dropped rapidly and gradually returned to normal
