It will be great if you can include in your bug report the following 2
piece of information:
1) Run your program with -Dprism.verbose=true. This will give us the
graphics hardware information of your system.
2) Run your program with -Dprism.order=sw. This will force JavaFX to use
its software pipe instead of hardware graphics acceleration. It will be
good to know whether the poor performance is due to use of d3d pipe.

Please file a bug. It might be possible for us to find a workaround,
although it might also be possible that this is just an unfortunate
limitation of Intel HD.

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?

I see. Interesting. Isn't there a switch to toggle it on JDK8?
There is no switch that can enable it if it is disabled by 'default'.
Assuming you are talking about JavaFX, right? Because you were
referring
to
Java2D in your reply.
No I am talking about 2D. What I meant was that maybe the
performance issue
is inherent in the card and the only reason it looks OK with Java2D on
Intel is
that we aren't using anything much at all of the Intel chip and are
doing
the work
on the cpu instead.

Java 2D does not (generally) enable D3D on Intel.
We tried for JDK 8 but there were problems and it was disabled
again in
8u40 I think.
JDK 9 EA builds (currently) still have it enabled to help get some
testing
so
if you are running an 8ux release you might want to switch to 9 to
get a
fairer comparison.

Hi guys,
I've noticed that clipping performance (Canvas GraphicsContext) is
extremely bad on an Intel HD graphics chip. One rectangular clip is
fine,
anything beyond that, or a spherical clip shape, will bring the
framerate
to its knees.
I notice no performance difference on my GeForce system, but on the
integrated chip my application is basically insufferable.
The same thing performed with Java2D experiences no performance
issues
on
neither system.
Any ideas?
