Hi there,

I've often read that java2d copies images that reside in vram back to system memory if frequently reads occur (like for aa or transculescent operations). Is there any way for tracing those copy operations?

In my case I render my own component into a large VolatileImage-backbuffer where just text (aa) and smooth-scales-images are not hardware-accalerated but these operations slow down painting performance really much. I would like to analyse this behaviour in detail and maybe see wether java2d puts/reads the image again and again or whats happening.

Thank you in advance, lg Clemens
