I would like to report a bug in Toolkit Pro in 19.2.0 in the Task Dialog class. I have upgraded the application I develop from Toolkit Pro 19.1.0 to 19.2.0 and noticed an issue in the CXTPTaskDialog class when icons are enabled with command link buttons. Here is a sample task dialog from my application using 19.1.0:

Upon upgrading to 19.2.0, this dialog becomes:

Notice how the text is much bigger and clipped which is the problem. I have diffed the CodeJock Task Dialog code between 19.1.0 and 19.2.0 and can see that the code which draws the icon has been reworked to use XAML buttons and a vector image but the XAML text it uses seems to use a hard coded font size:

<StackPanel Orientation='Horizontal'>
<Viewbox Stretch='Uniform'>
  <Canvas Width='16' Height='16' Canvas.Left='0' Canvas.Top='0'>
    <Line X1='0'  Y1='8'  X2='16' Y2='8' Stroke='#3E79B4' StrokeThickness='2' StrokeEndLineCap='Round'/>
    <Line X1='11' Y1='3'  X2='16' Y2='8' Stroke='#3E79B4' StrokeThickness='2' StrokeEndLineCap='Round'/>
    <Line X1='11' Y1='13' X2='16' Y2='8' Stroke='#3E79B4' StrokeThickness='2' StrokeEndLineCap='Round'/>
  </Canvas>
</Viewbox>
  <TextBlock Padding='5, 0, 0, 0' FontSize='16' FontQuality='ClearType' VerticalAlignment='Center'>%s</TextBlock>
</StackPanel>

which seems to be causing the problem along with the wrong calculation of the button ideal sizes. This issue is not related to high DPI and occurs when my display is set to 100 percent.

The only workaround I have found is to disable icons on the command link buttons using:

taskDlg.EnableCommandLinks(TRUE, FALSE);

which results in the following:

but ideally I would link the icon back on the buttons. I have looked at the code and I can change the code by overriding the virtual function CXTPTaskDialogClient::CreateLinkButtons in my class, but ideally I would like this issue fixed or a feature added which allows the old 19.1.0 behaviour of command link icons back.
