hi there,

i create a bufferedimage object, paint onto it, then redisplay it
periodically.  this works fine for a while; after moving the frame to
the background, then back to front etc, i totally lose the contents of
the buffer: all pixels are lost replaced with a white fill (component
background color).  now, i don't mind that this happens sometimes as
long as there would be a way to determine that the contents is lost,
in which case i would simply repaint the buffer.  however, i am using
bufferedimage, not volatileimage, and i don't know of a way to check
that the image has lost its content.

on the other hand i tried using volatileimage, with either
ImageCapabilities(true) and ImageCapabilities(false), but in this case
the drawn contents is not displayed even once; what's more, every time
i check contentsLost() it returns true, and yet the contents is not
displayed after painting into it.

i'm using1.4.1_02-b06 on windows xp, graphics card is nvidia geforce4
4200 go with 64mb of video memory.

here's the code for creating the buffered and volatile images:

     GraphicsEnvironment Ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
     GraphicsDevice Gd = Ge.getDefaultScreenDevice();
     GraphicsConfiguration Gc = Gd.getDefaultConfiguration();

//      __local.image = new java.awt.image.BufferedImage(
//          G.getClipRect().width,
//          G.getClipRect().height,
//          java.awt.image.BufferedImage.TYPE_INT_ARGB
//          );
//      __local.image = Gc.createCompatibleImage(
//          G.getClipRect().width,
//          G.getClipRect().height,
//          Transparency.TRANSLUCENT
//          );
       __local.image = Gc.createCompatibleVolatileImage(
           G.getClipRect().width,
           G.getClipRect().height,
           new ImageCapabilities(true)
           );

any ideas?
thanks
