Texts rendered as filled rectangles

Hi,

I have a problem when rendering texts in my applicatiion based on WorldWind (so it uses JOGL 1.1). Usually, texts are rendered properly but sometimes they are rendered as filled rectangles (see screenshot bellow) after a few seconds if I leave the application running without interacting with the view.



Then, when I interact with the view (zoom, pan, ...), texts are rendered properly again.

I think something is wrong when I initialize the rendering of the text but I have checked at my code (FastTextRenderer.java) andI don't see where the problem is. Can someone help me ?



Regards
