JDK-8193445 Performance Test (CSS applied redundantly)

[Scott Palmer]

JDK-8183100 is a fixed issue.  But it basically undid the fix for https://bugs.openjdk.java.net/browse/JDK-8151756 <https://bugs.openjdk.java.net/browse/JDK-8151756>
I think you mean to ask when JDK-8193445 might be addressed.

I too would like to see the performance return, and actually I’m hoping it can be made better than it was before. 

Performance improvements and a JNI mechanism to get at native window handles are the first two items on my wish list.  Though extendable media support could potentially beat out the window handle thing.. I only need a native window handle so I can do native rendering of video frames from a non-JavaFX source.
