sounds like a buffering problem. look into double buffering. i understand that java 1.6 might have some classes that take care of all that for you without you having to do much thinking about how to implement double buffering

myorak, I think the OP is talking about the new native splash screenfeature in 1.6... in which case I dont believe you have any controlover anything let alone double buffered rendering.

ah, i havent looked into new 1.6 stuff yet. what is the advantage of the native splash over making one yourself? maybe in this case it would be easier to just make one yourself?

Does it flash if you unjar the app and launch it from the command line with a splash screen image filename?

I've only played around with this new feature and haven't use the jarred version,

but I haven't seen any flashing.

Do you have any code that manipulates the java.awt.SplashScreen object,

or is that manifest entry the extent of your splash screen involvement?

The spash screen comes up before the JVM and as the app is loading.

I guess its just there to pacify people who think the JVM and App Startup

is too slow. I know people at my job have actually said to me when

running a Java app "why does it load sooo much slower than a VB

app?" when in actuality it came up in an eye blink.

I guess VB apps load in half an eye blink, lol.

I thought that because the SS comes up before the JVM (or concurrently

or whatever) that you couldnt control it?

"Java 6, provides a solution that allows the application to show the splash screen much earlier, even before the virtual machine starts."

As for why:

"Before [a java programmed AWT] splash screen can pop up, the application has to load and initialize the JVM*, AWT, usually Swing, and perhaps some application-dependent libraries. The resulting delay of several seconds has made use of a Java technology-based splash screen less than desirable."

What happens is that the Image comes up first and then your code that

manipulates the image starts a moment later. For example, you may

be doing a little animation, or writing on a clear spot on the image.

So you definitely can combine splash screen code with an initial image.
