When I start a JavaFx application, the application starts with size 0,0. I can then enlarge it (when I find it).
This happens with all JavaFx applications.
To see that behavior download the samples from: http://www.oracle.com/technetwork/java/javase/overview/javafx-samples-2158687.html
I've tested it with Ensemble:
java -jar Ensemble.jar
My Xpra is compiled from trunk r9187.
I cannot reproduce this with 0.14 or with trunk so I am lowering the priority, my desktop environment is cinnamon on Fedora 20.
Please include more details so we can investigate this issue you are having, see wiki/ReportingBugs for guidelines.
It may be worth including the client and server logs with -d window.
Logs with -d window
Please find the -d window logs attached.
I'm using a gentoo system.
Please see wiki/ReportingBugs, comment:3 is nowhere near enough information for me to do anything with it.
Sorry for not providing enough information. The client log was missing due to an error of me.
In the mean time I found out, that the problem is related to the version of the JVM (java virtual machine).
Oracle JDK 1.8.0.45 (also tried 1.8.0.40) has the problem. Oracle JDK 1.7.0.80 is OK.
Running Ensemble.jar against a "real" X11 server is OK with both JVM versions.
I my tests I saw no dependency to xpra version (tried back to r5826). I saw no dependency on the client (linux/osx).
Can you try again please by using a java 1.8 jvm?
Confirmed with jdk8.
This sounds similar to #705, but sadly, using the wm-name=Sawfish does not help here.
Here comes the server -d window debug log extract for this:

So we create a 1x1 window as we're told... Not sure where we're supposed to be getting the "correct" size from.
Could be related to #881.
Got it, not sure how I missed it earlier. Using:
XPRA_X11_DEBUG_EVENTS=ConfigureRequest xpra start ...
We see:
ConfigureRequest event 0x6db : <X11:ConfigureRequest \
{'delivered_to': '0x44', 'send_event': 0, 'type': 23, 'detail': 0, 'height': 700, 'width': 1020, 'window': '0xa00003', 'above': 0L, \
'y': 0, 'x': 0, 'serial': '0x6db', 'border_width': 0, 'value_mask': 12L, 'display': ':10'}>
delivering event to parent window: 0x44 (signal=child-configure-request-event)
not forwarding to XpraServer handler, it has no child-configure-request-event signal (it has: ('xpra-cursor-event', 'xpra-child-map-event'))
forwarding event to a Wm handler's child-configure-request-event signal
do_child_configure_request_event(<X11:ConfigureRequest {...}>) value_mask=Width|Height, should be handled by the window model
forwarded
ConfigureRequest event 0x6db : <X11:ConfigureRequest \
{'delivered_to': '0x44', 'send_event': 0, 'type': 23, 'detail': 0, 'height': 1, 'width': 1, 'window': '0xa00003', 'above': 0L, \
'y': 291, 'x': 770, 'serial': '0x6db', 'border_width': 0, 'value_mask': 3L, 'display': ':10'}>
delivering event to parent window: 0x44 (signal=child-configure-request-event)
not forwarding to XpraServer handler, it has no child-configure-request-event signal (it has: ('xpra-cursor-event', 'xpra-child-map-event'))
forwarding event to a Wm handler's child-configure-request-event signal
do_child_configure_request_event(<X11:ConfigureRequest {...}>) value_mask=X|Y, should be handled by the window model
2015-05-23 22:29:06,579 forwarded
So we get two configure request events: one for (Width|Height) and one for (X|Y), but they are delivered to the root window (0x44) instead of the window model. And so we then decide to not act on it in Wm (which listens on the root window) because the window model's handler should be dealing with it.
And now we go down the rabbit hole:
_update_client_geometry will only honour the update before setup_done and this happens after...
window.get_position() still returns 0x0 after we've moved the window to its requested location - looks like a bug, the size is correct as we get the value from the actual-size property
size_notify_clients timer... and by the time it fires, the client has configured the window in its initial size + location (which is 0x0 at 0,0..), so we don't send it
What a mess!
with this hack of a patch, the window shows up with the right size and position
r11301 + r11302 + r11304 fix this issue and I am able to run the examples with JDK8
@mptei: please close if this works for you.
(applied to v0.15.x in r11309)
I can confirm that it works. I've testet with r11347.
Thanks for fixing!
