Hi All,

I was trying XTrans framework and ran across a setting required for XTrans but caused a 100% CPU utilization (even with all the XTrans code removed) for another important internet app called WorldWind for Java. I am running in 1.6.0_07 using JNLP and the properties XTrans needed which cause the problem for WorldWind is:

<property name="sun.java2d.opengl" value="True"/>
<property name="swing.bufferPerWindow" value="false"/>

Is there some other setting or config I could try that might be less an issue with Mutiple Java2D components/frameworks using JOGL?

Many Thanks,
-Tony

Unfortunately you are entering uneven terrain here. The java2d OpenGL pipeline is not as rebust as it should be. Try to disable the Java2d OpenGL pipeline. This might do the trick but could lead to bad performance or some features not working anymore.

I agree with you. For JOGL, only set noddraw at true but don't use the OpenGL pipeline.

Hi All,

Many thanks for the reply. The app seems to respond with an error about requireing the openGL pipeline being needed and I tried disabling ddraw in conjunction with stting openGL pipeline being set to true but the problem persisted.

There were other issues where the skins seemed to go haywire and throw exceptions and I had video that would not update when I had muliple child windows and the non-video window was selected.

I will take another approach to solve my desired enhancement to use Java2D with JOGL.

Best Regards,
-Tony
