Thanks Fred. Great information.

I tried -Dsun.java2d.accthreshold=0 as you described. It works fine when I have 
enabled the opengl pipeline using -Dsun.java2d.opengl=true, however if I have 
the d3d pipeline enabled with -Dsun.java2d.d3d=true then I seem to loose 
acceleration for all loaded images. Normally the d3d pipeline is just about as 
fast as the opengl one. I have tried most of the other runtime flags, in many 
combinations, however any time I have accthreshold set to 0 with the d3d 
pipeline enabled my images are very slow to draw.

So I think I am going to go for the workaround. Which surface should I render 
the image to to force it to become managed? I do not want to render to the 
screen (other things are going on). Can I just render to another Buffered 
Image? I don't think so, I think I need to render to an accelerated surface. Is 
there a 'proper' one to use?

Regards,

Alistair
