Yes, Windows Vista.
But for me it looks like there is some space for optimizations. Why do all
components have to be repainted in case of a single repaint?
There's definitely room for optimization there, especially on Vista.
The way Windows does translucent windows is through layered windows.
Basically if you want to update something in such a window you need
to copy whole bitmap representing the window. Currently we
re-draw this bitmap on every repaint.
We should be able to optimize this to use Swing's back-buffer for this
purpose but there are issues with it which couldn't be resolved
for 6u10. We may look into it for 6u14.
