thanks for the explanation

for example on nvidia cards (not Quadro) rebinding the Texture to the
Pixmap (after each damage event) , cased the content of the pixmap to
be copied to the texture memory on the graphics cards.
currently we create a shared pixmap using redirected window pixmap,
each time a damage occure we copy the region affected by the damage to
the Java3d image data, which is binded to a texture. this will lead in
each frame the content of the image to be transfered to the texture
