Your second idea isn't as bad as it sounds. You can make it faster if you scroll your offscreen image with copyArea() and then only draw the tiles at the edges. In worst case that's only 35 tiles /frame.

What kind of image are you using as your backbuffer ?

Hi,
i have submitted the Bugreport.

I have also found another solution for smooth scrolling.
I'm using the following function:

Image image;
Graphics2D g=image.createGraphics();
private void copyArea(int x,int y, int width, int height,int dx,int dy)
       {
         int x1=x+dx;
         int y1=y+dy;
         int x2=x1+width;
         int y2=y1+height;
         g.drawImage(image,x1,y1,x2,y2,x,y,x+width,y+height,null);
       }

It works great with Images with a resolution about 800x600 (same speed as with copyArea but without slowdowns). With my new cpu(XP1600)  i can use the function for even bigger images. I'm not really sure why the speed is cpu dependent,but i didnt benchmark it very good.

I hope it will help you.
