Description
If you scale a node with a Blur effect (BoxBlur, GaussianBlur, MotionBlur) on it, the node will show signs of pixel stretching from a default 72 DPI, ignoring whatever scale it would have had without the reflection effect.

Note that a blur effect will obscure the DPI of the original anyway so this only shows up with small blur radii.
Comments
This is essentially a direct duplicate of RT-13275 which was fixed in 8u20.

See the TestEffectDPI.java test case attached to RT-24009 for a test case that demonstrates this issue, even on non-HiDPI screens.
