I upgraded my video drive this morning and that didn't seem to make any difference. I am trying to find an example of how to use the dirtyTextureObject() function but am having a hard time. Would anyone be able to share a code snipit on the correct way to implement this function? Thanks, Roger

You might want to try upgrading your driver. I worked around the problem by calling dirtyTextureObject() on each texture in the model whenever I created a new window, forcing the driver to reload the texture data from system memory. I think the driver got confused with shared contexts and this function was an effective reminder of what the texture data was supposed to be.

My application adds/destroys views dynamically and I am having an issue when I have two views loaded with the same terrain/textures (for example a terrain) when I close one view the textures in the 2nd view all get removed from the scene. The only way I am able to get the textures in the remaining view to reload is to close the view, leaving none open, and opening a new view. This process destroys and recreates the composite viewer. I have tried calling setUnrefImagedataAfterApplyPolicy(true, false) on each view as they are created but this has not helped resolve the issue. Can anyone provide any advice to help with this? Thanks, Roger
