Full screen flickering

Question

Hello, I'm having some full screen issues like so m any people. I just finished converting my game to full screen mode, but now there are some problems with flickering which seems to be coming from when new images are loaded. Has any one else ever experienced a problem like this? I believe I'm going to use media tracker to finish loading the images and hope that helps. But, the computer also seems to stop updating the screen sometimes in which never happened when it was windows.
These are the lines I used for buffering stratagie---
(in main method)
GraphicsConfiguration gc = device.getDefaultConfiguration();
setUndecorated(true);
setIgnoreRepaint(true);
device.setFullScreenWindow(this);
this.createBufferStrategy(2);
bufferStrategy = this.getBufferStrategy();
Thread th = new Thread (this);//other calculations
th.start ();
graphicsThread.start();//paints graphics
--------------------------------------(this is for drawing graphics)
class graphicsThread implements Runnable {
private Thread thread = null;
public void start() {
if (thread == null) {
thread = new Thread(this);
thread.start();
public void run() {
thread.setPriority(9);
while(true) {        
Graphics g;
g = bufferStrategy.getDrawGraphics();
render(g);
g.dispose();
bufferStrategy.show();
I am unsure if I want to try Volatile images or not. The frame rate is a bit low, but not unexceptable as I'm working on an RPG it isn't that important. So if anyone could help me with BufferStrategies I would be greatly obliged!

Answer 1

yes, u have to ensure your images are fully loaded before you start rendering them.
MediaTracker will do this for you.
Alternatively you can load your images synchronously using ImageIO.read(..)
(Note however, images returned from ImageIO are not ManagedImages - they must be copied to a ManagedImage before they will be elligable for hardware acceleration)
As for the app. failing specifically when in fullscreen mode.
What Java version are you using?
There are alot of bugs related to fullscreen, most have been fixed in Java1.4.2 so i'd try upgrading to that and see if it fixes your problem.
And with regard to the frame rate, if you are doing it right, you should be able to render several 1000 images at 60fps without to much hassel.
Just make sure all your images are either ManagedImages or VolatileImages (depending on the circumstances, each have their uses.)
