September 2, 2020 ยท View on GitHub
-description
Gets or sets a value that enables a debug setting that visualizes overdraw operations. This visualization is useful during application development for detecting layout, animation, and other operations that are graphics processing intensive.
-property-value
true to enable the visualization, otherwise, false.
-remarks
Use this property as a debugging aid to visibly detect areas of the UI where applying a CacheMode for textures might be useful. For more info, see "Cache static content" section of Optimize your XAML markup.
OnLaunched is a good place to change DebugSettings values.
