Oh. I forgot to mention that I'm using the composite viewer in single threaded mode.

This context is created first, with no inherited window data. When I create a new view, I create a new context for this view and set the sharedContext member to the shared context. I set the inherited window data too for embedding the view in the desired window. Carsten.

If you are creating a new context how are your creating the new context? Robert. On 27 August 2012 10:13, Carsten Scharfe <cscha...@dspace.de<mailto:cscha...@dspace.de>> wrote: Hi. I've come across a strange behaviour regarding NVS cards from nVidia. On some occasions I get corrupted polygons, when initializing and showing a new view, which is rendered by a composite viewer. I've attached 2 screenshots showing the corrupted rendering and how it should be. Strange enough, this behavior can be observed only on NVS cards. Quadro Fx, Quadro and GeForce cards do not show this issue. Has anybody had the same or similar problem and can give me some hints on what went wrong? I definitely need help here. I use OSG 3.0 on Win7. The scene is rendered with some shaders. Our application has an edit mode for scene assembly integrated, which, if activated, creates a new view for editing purposes and adds this view to the composite viewer. Our edit mode is rendered in a different window and thus requires it's own view. The polygon corruption occurs on this occasion. If the edit mode is deactivated and activated again (the view is only created once on the first activation) the rendering is as expected. Any comment is welcome. Thanks in advance.

Es wurde kein Dateiname angegeben. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org<mailto:osg-users@lists.openscenegraph.org> http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
