Hi Maik,
this is a known problem described in
6635462: D3D: XOR rendering is extremly slow
Unfortunately there's no solution at this point.
I would suggest to avoid using xor mode. In your case
you can just draw the rectangle and then repaint the
affected area when it needs to
Hi Dmitri,
can you give me a hint how I redraw only the affected area in Java? I was
looking for something like invalidateRect but I didn't found it.
Currently I circumvent my problem by re-rendering the whole image. This works
better but is far from the performance with d3d=false and XOR
Hi Dmitri,
I will try that, tomorrow.
Thank you for your help!
Maik
