In previous post I mentioned Kevin, I meant Jim. In the last update from Jim for this bug, he mentioned that it could be related to synchronization and frame rate vs rendering. https://bugs.openjdk.java.net/browse/JDK-8178805
I tried to run tests to prove this out, but was not able to notice any anomalies with either the frame rate nor the MasterTimer. The method used to test the MasterTimer by passing it an AnimationTimer that stores the delta time. A hiccup in the MasterTimer should be noticed from the AnimationTimer by storing the delta times and plotting them. While gathering those times, might as well collect the instant FPS and plot those as well. Would the synchronization issue be notied through either of these methods or am I off the mark here? The program in the link below does what I mentioned. When you run it either wait for the program to plot the points or click on the black background to force the points to draw on the screen (red is delta time from the MasterTimer and light green is the FPS). I like to wait till the jitter happens then click the background right away. After running many tests I do not see any hiccups in the plots that match the noticed occurrences of jitter. Does this mean that it could be a render issue? https://pastebin.com/XjiqE9yu From: Jose Martinez <jmartine_1...@yahoo.com> To: Kevin Rushforth <kevin.rushfo...@oracle.com> Cc: "openjfx-dev@openjdk.java.net" <openjfx-dev@openjdk.java.net>; Lord Chaos <joearo...@gmail.com> Sent: Sunday, May 7, 2017 12:03 AM Subject: Re: PathTransition jitter Looks like I am unable to update the Jira ticket so I guess I'll update the bug in here. Kevin mentioned that there is some relief if "-Djavafx.animation.fullspeed=true" VM option is used. I notice that it does improve but not remove the problem. Also, the jitter is not limited to PathTransition. In the example below the problem is reproduced by using Timeline and no PathTransition. Since like this is not just an issue with PathTransition, would it be possible to bump up the priority on this? The Jira mentions the fix is scheduled for Java 10. Does this affect all animation in JavaFX? Is there anyway to move objects on the screen without jitter? private void pathJitterBug(Stage primaryStage) { // Circle circle = new Circle(30, Color.RED); // Path path = new Path(); // path.getElements().add(new MoveTo(100, 100)); // path.getElements().add(new LineTo(500, 100)); // path.getElements().add(new LineTo(500, 500)); // path.getElements().add(new LineTo(100, 500)); // path.getElements().add(new LineTo(100, 100)); // // PathTransition pathTransition = new PathTransition(Duration.seconds(10), path, circle); // pathTransition.setCycleCount(Animation.INDEFINITE); // pathTransition.setOrientation(PathTransition.OrientationType.ORTHOGONAL_TO_TANGENT); // pathTransition.playFromStart(); // Circle circle2 = new Circle(20, Color.BLUE); Timeline tl = new Timeline( new KeyFrame(Duration.ZERO, new KeyValue(circle2.centerXProperty(), 125), new KeyValue(circle2.centerYProperty(), 125)), new KeyFrame(Duration.seconds(5), new KeyValue(circle2.centerXProperty(), 425), new KeyValue(circle2.centerYProperty(), 425)) ); tl.setCycleCount(Timeline.INDEFINITE); tl.setAutoReverse(true); tl.playFromStart(); // Circle circle3 = new Circle(20, Color.GREEN); Timeline tl2 = new Timeline( new KeyFrame(Duration.ZERO, new KeyValue(circle3.centerXProperty(), 425), new KeyValue(circle3.centerYProperty(), 125)), new KeyFrame(Duration.seconds(5), new KeyValue(circle3.centerXProperty(), 125), new KeyValue(circle3.centerYProperty(), 425)) ); tl2.setCycleCount(Timeline.INDEFINITE); tl2.setAutoReverse(true); tl2.playFromStart(); // Group root = new Group(); // root.getChildren().addAll(circle, circle2, circle3); root.getChildren().addAll(circle2, circle3); Scene scene = new Scene(root, 600, 600); primaryStage.setTitle("Hello World!"); primaryStage.setScene(scene); primaryStage.show(); } From: Kevin Rushforth <kevin.rushfo...@oracle.com> To: Jose Martinez <jmartine_1...@yahoo.com> Cc: "openjfx-dev@openjdk.java.net" <openjfx-dev@openjdk.java.net>; Lord Chaos <joearo...@gmail.com> Sent: Friday, April 14, 2017 9:29 AM Subject: Re: PathTransition jitter And here is the direct link in JBS: https://bugs.openjdk.java.net/browse/JDK-8178805 -- Kevin Jose Martinez wrote: > Thank you Kevin. > For those interested here is the bug report: > http://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8178805 > > > > > From: Kevin Rushforth <kevin.rushfo...@oracle.com> > To: Jose Martinez <jmartine_1...@yahoo.com> > Cc: "openjfx-dev@openjdk.java.net" <openjfx-dev@openjdk.java.net> > Sent: Thursday, April 13, 2017 7:49 AM > Subject: Re: PathTransition jitter > > One more thing: all bugs were transfered from the old JavaFX JIRA intoJBS in > June 2015.
