background image with runnables ugliness

[poe]

Hi,I`m using java awt only for simplicity and I have a animation issue.Displaying a animation on to a blank background/set background color works fine when double buffered and media tracked.When I have a image as the background and try to display my animations on top,ugliness.
Any suggestions appreciated.

What does this question have to do with Threads and Synchronization, which is the subject of this section of the forum?

The animation/s is a runnable thread.

That doesn't make it a Threads and Synchronization issue. Moving to Java 2D.

Whatever made you decide that AWT is simpler than Swing, which replaced it more than 10 years ago?

To get better help sooner, post a SSCCE (Short, Self Contained, Correct (Compilable), Example) that demonstrates what you call 'ugliness'. Before you do that, go through these:

Don't start two threads for the same problem. I'm merging the threads.
