We have rendering problems with the OpenGLES accelerated Silverlight on the AM3359 EVM platform: The BSP comes with the environmental flag bsp_xrplugin_opengl=1, which configures the XAML rendering engine to use OpenGLES. However when using this flag, we are experiencing some artifacts and graphical rendering issues. For example when pulling up the Microsoft (Silverlight) soft input panel, for the first time it looks like the image below.
There are also seems to be some kind of event problems, e.g. when pressing button ‘A’ and then ‘S’ in a sequence. The ‘A’ button is pressed” visually when ‘S’ is pressed down. (This picture is taken from the EVM AM335x board).
In our Silverlight application we’ve had issues with graphics disappearing, and sometimes areas are filled with black. The application is written in C# using the XAML in Hand framwork, but we have also created a C++ Silverlight test application which yields the same results - so it seems to be a Silverlight rendering problem.
When turning of the bsp_xrplugin_opengl flag, the graphics renders properly (XAML OpenGLES rendering disabled), but to a higher CPU cost which we do not want.
Do we need to add additional WCE7 components, or set any other enviromental variables?
We have installed all the latest WCE7 updates.
Please advice.
