Re: PathTransition jitter

2017-05-07 Thread Hermann Maier

Thank you very much, Itai, for this straight tip, because testing some JavaFX 
applcations with (X)Ubuntu 17.04 (Mesa 17.0.1 and Xorg>1.18.4) didn't show 
any bad behavior like the aforementioned resource leak.
So the only question remaining is why nobody mentioned this as a possible 
solution to JDK-8161914 on it's JBS page?


Anyway, I don't intend lead this off-topic, so I can only confirm the 
jittering issue.


Cheers,
Hermann

happening on my system too and it's very annoying (e.g. I made a game with
JavaFX and realized this too late…). Thus I would suggest that raising the

However, when I use the Software Renderer there's nothing like described

Re: PathTransition jitter

2017-05-07 Thread Jose Martinez

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?

2017-05-07 Thread Hermann Maier

I can reproduce the problem as well on my system with (X)Ubuntu 16.04 64-Bit 
and Mesa 12.0.6, with JDK 8u131.
Also, the CPU usage of the Java process and the Xorg process is increasing 
constantly until the application gets completely laggy and unusable (like 
every application that is using some JavaFX animation under Linux with the 
hardware renderer). This bug is already known [1], the resource leak is 
happening on my system too and it's very annoying (e.g. I made a game with

I think it is very unusual to handle unqualified exports as something 
special, different from qualified exports. I know what the reasoning is: 
if a package is exported unconditionally (to everyone) then it is part 
of public API and so the trampoline may access members of that package 
on behalf of anyone. But such reasoning is just a consequence of the 
lack of a finer-grained (per-module) access support in JavaFX. I know it 
is too much to ask for JDK 9, but could JavaFX in say JDK 10, given 
current API, somehow determine on whose behalf it is making the 
trampoline access? If it could, then the trampoline could allow 
qualified exports to be effective too.
