falling into the abyss of reality

The following gives erratic results - and I was wondering why (whether it would manifest itself as a bug on platforms other than windows - where GraphicsConfiguration objects don't all use the same ColorModel):-

1  
2  
3  
4  
5  
6  
7  
8  
Frame f = new Frame();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
gd.setFullScreenWindow(f);
gd.setDisplayMode(new DisplayMode(800,600,32,60));
gd.createBufferStrategy(2);
GraphicsConfiguration gc = ((Graphics2D)f.getBufferStrategy().getDrawGraphics()).getDeviceConfiguration();
System.out.println(gc);


sometimes I get :-

1  
Win32GraphicsConfig[dev=Win32GraphicsDevice[screen=0],pixfmt=1]


othertimes I get :-

1  
Win32GraphicsConfig[dev=Win32GraphicsDevice[screen=0],pixfmt=0]


I guess pixfmt=0 is the pixelformat for describing the front page of a flipping strategy, I say that because pixfmt=0 is not an option available normally through graphicsDevice.getGraphicsConfigurations().
pixfmt=1 is avaiable through said method, (it is the default GraphicsConfiguration - atleast on my system)
If I use the Frame constructor Frame(GraphicsConfiguration gc), the GC I passed in is the GC i get back from graphics2d.getDeviceConfiguration().

Is it giving indeterminate results, because the front and back buffers in a page flipping strategy have different pixel formats (or atleast, different GraphicsConfiguration objects), and I am randomly geting either the front buffer, or the back buffer. (if this is the case - it seems like a bug in the making :S)

:edit:

btw, this has little relevance to any app. im writing - I'm just trying to figure out exactly what is happening underneath the bonnet [US: hood] of java2d Cheesy

If only I knew what I'm talking about!

yeah, it's really strange that you're getting random results. I'd expect it to be consistent..
