Ok. Maybe the problems I am experiencing now with JavaFX are the reason why D3D is not enabled for J2D?
I think Intel Graphics are rather widespread among laptops, so I'm a bit surprised at the huge performance drop (from solid 60 FPS to 8 once I use a spherical clip shape). I'd think Intel Graphics hardware form part of the test set. I'm using a fairly common laptop (especially around business circles) Dell Latitude E6410. Any chance of this being investigated or do you think I will have to settle with a workaround?
