ProductRadButtons for WPF

Description

Buttons can appear distorted or pixelated on Dell machines. This behavior can also be present in some of the native WPF controls.

Solution

To prevent this behavior from occurring, there are two approaches that can be taken.

The first approach is to blacklist your application. To do so, you can follow these steps:

  1. Open the BlackApps.dat that can be found on this path: C:\ProgramData\A-Volute\DellInc.AlienwareSoundCenter\Modules\ScheduledModules\Configurator\BlackApps.dat

  2. Append the name of your process at the end of the file (for example, MyApplication.exe) and save it.

The second approach is to set the System.Windows.Media.RenderOptions.ProcessRenderMode property to System.Windows.Interop.RenderMode.SoftwareOnly before showing any WPF windows.

Set the RenderOptions.ProcessRenderMode property

C#
	System.Windows.Media.RenderOptions.ProcessRenderMode = System.Windows.Interop.RenderMode.SoftwareOnly;
