Recently I came across with an issue in Silverlight application. When I was setting application to Full Screen mode, the Silverlight was changing dropdown and child page background color to red color.
I did research on this and found that by mistake I enabled Cache Visualization in my application and due to this uncached objects were tinted.
When GPUAcceleration is enabled and you want to visualize cached and uncached object in your application, you can set enableCacheVisualization to “true” , this will show uncached object in tinted color and cached object will be displayed normally.
<object data="data:application/x-silverlight-2," id="Object1" type="application/x-silverlight-2" width="100%" height="100%">
<param name="source" value="ClientBin/Example.xap"/>
<param name="onError" value="onSilverlightError" />
<param name="minRuntimeVersion" value="3.0.40624.0" />
<param name="enableGPUAcceleration" value="True" />
<param name="enableCacheVisualization" value="True"/>
</object>
The CacheVisualization should not be enabled in production environment, this is basically used for debugging and troubleshooting the GPU Accelerated application.
