I have a localized JavaFX application and this is happening to one user, but something similar is reported from other users from time to time:
As you can see from the image, the application is localized correctly (buttons, table headers..) but the text in the middle of the table (left) is gibberish, it's a simple Label styled through css. On the right the same app version running on my computer where everything is fine.
The application runs on a bundled jlinked JDK 11.0.8. I tested it on Linux, Windows and Mac and I cannot reproduce.
Any idea of what could cause this behavior or what I can do to investigate it?
Thanks

I am having problems using the Ikonli icon packs. I am creating FontIcon objects and then using those to set the graphics on buttons. Icons taken from the FontAwesome5 pack work great. Icons taken from the Material2 pack seem to shift somehow - for example, I try to get mdal-6_ft_apart but what actually gets displayed is mdal-loyalty. And no matter which Icon I load from MaterialDesign2, all I see is an empty box.
I'm running this through Eclipse, and everything looks fine when stepping through with the debugger. This is the value of the button graphic:
ObjectProperty [bean: mdal-6_ft_apart:15:0xffffffff, name: iconCode, value: MDAL_6_FT_APART]
and yet, on the screen, it's something completely different.
This is a Maven project using OpenJDK 16 and JavaFX 16. I've tried loading just a single icon pack instead of all 3, but no difference. Also, there are never any errors retrieving the icons. The ServiceProviders are all found, and the icons are available.
I made a small Hello World program and everything runs fine, so it's definitely an issue with my program and not the library. But I have no idea what the problem is, and I've been staring at this for almost 2 hours. Has anyone come across this before? I'd appreciate any help, because I'm out of ideas.
Answering this myself in case it saves someone else some time. I was installing the Ikonli library in order to replace the FontAwesomeFX library that is no longer available. I had gotten partway through replacing the icons when I ran the app in order to check the progress, and that's when I saw the errors.
The problem turned out to be an interference between the two libraries - FontAwesomeFX was throwing of Ikonli. The icon shift didn't actually occur until the code displayed a FontAwesomeFX icon, which made it seem a little random depending on the order I would open the dialogs when testing. I'm assuming an issue with the Service Handlers, though I'm not positive because I stopped troubleshooting once I realized the problem and just finished the replacement.
Once I stopped displaying FontAwesomeFX icons and the dependency was removed, Ikonli worked fine.
I am having a display issue with Infopath. My section lines and section text disappear in the form designer. The lines are initially there but then disappear after I click a few times and scroll. They still exist and can be clicked but I cannot seem them. I am not sure right now what exactly is causing them to disappear.
I am able to get them back again by switching views. This problem occurs both with infopath 2010, and 2007. It also happens to different forms. So it appears to be some sort of display issue. I have not noticed display issue's in any other programs.
I think the likely cause is because I recently formatted my computer, swapped graphics cards for the same model number but what looks like a newer revision because the fan failed on the last card. My specs may be relevant: I am using an AMD FirePro V4900, latest driver 13.352.1009 as of posting. 3 Monitor setup. Windows 7 x64.
Has anyone else run into this and found a fix?
We have an application running flex sdk 4.5 and have recently encountered an issue with textInput fields which we have not been able to reproduce on our end for the better part of a month now.
Here are the symptoms:
Users opens an input form which contains several input fields (combo boxes, calendars, text inputs, etc)
User clicks inside a text field
Users types (obviously!)
** Nothing appears in the text input - we have validators on some of these fields and they do kick in properly (ie. user sees red box around textInput disappearing)
User moves cursor outside of text input field and text appears
Give or take, this is the test case we've been provided. We have been unable to reproduce this and I'm reaching out to see if anybody has heard of issues like this in the past.
They are running our flex application in the following environment:
Windows XP SP3
IE 7.0.5730.13 (locale = en-gb)
Flash Player 10.3.181.14
Upgrading either of these components is not an option. Installing the flash player debugger is not an option either.
Now we've setup a pc exactly the same way as they have on their end and still haven't reproduced. So we're really stuck at this point :)
Any suggestion is greatly appreciated. I'll provide any additional info needed.

Feb. 2nd 2012 - Update
As I noted in my comment reply to shaun, it seems our customer was more or less precise in their description of the issue. We ran a webex session with them this morning and actually saw the issues first hand.
Here's what happens:
- User loads our application via its url
- User is able to input data and pretty much do any function for a 'random' time period
- All of a sudden, the issues start (there are more symptoms than just the one I originally mentioned):
1. Users type in text input fields and they won't see the text appear until they move the cursor out of / into any other component (could be entering an hbox, exiting a text input field, etc)
2. Combo boxes behave more or less the same. They can drop them down, but then the mouse wheel no longer refreshes the list. It actually scrolls in the background, but until the user moves the mouse, the list does not refresh
3. We also communicate between the server and client via an amf channel. The events make it to the client, but again, they won't see the screen refresh until they move their cursor.
So basically, the application still seems to work, but the screen is no longer refreshing. Could it be something to do with an invalidate / update of the display list that doesn't kick in? We'd like to get them to install the debugger version of FP, but that doesn't seem to be an option.
Another thing to keep in mind: they have a VERY bad internet connection. They average around 1-1.5mbps (megabits) which is enough for our app, but I just thought I'd let you know.
We learned that they also use a Citrix presentation layer to deploy IE 7 to the end users. We've received confirmation from the end user that even if they launch IE on their workstation (not through citrix), they get the issue also.
Another note is that we've seen no errors in our web server, jboss or application logs...
So that's the update I've got... anyone have more thoughts on this? We've more or less discarded the fonts being an issue at this point since the issue affects more than just 'fonts'. Is everything on the screen not updating anymore.
I have an example application that came with Qt (dialogs/standarddialogs) and modified it so that it displays dialog on every screen:
for(int i=0;i<app.desktop()->screenCount();i++)
{
Dialog* dialog = new Dialog(app.desktop()->screen(i));
dialog->show();
}
return app.exec();
When testing on Xnest on application default screen (the one from which the application has been started) everything works ok. However, on the other screen the icons in message boxes are not displayed correctly.
The problem can be reproduced on both solaris and linux. However, when I try Xephyr instead of Xnest the problem disappears (on linux). On the other hand this is not a problem with Xnest itself as on Exceed the problem can also be reproduced (but the icons are not displayed at all).
Has anybody seen this kind of problem? Do you think it might be a problem with Qt or configuration of X server? Or maybe I need to compile Qt with some special options?
It seems to be a bug in Qt X11 graphics system. If I set QT_GRAPHICSSYSTEM to raster the icons are displayed properly.
A user complains they can't paste into one particular text box on a form and that this is a change in behavior that occurred three months ago. I can't reproduce the error. I've tried long text, short text, plain text, formatted text, everything works. I did fix some poorly formatted HTML, but it didn't change their problem.
The user and I are both using XP/IE7. The application uses a proprietary MVC framework with C# on .NET 1.1. The UI only works reliably in IE. (I tried Opera and the paste works, I can't get logged in with Firefox to get to the screen.)
Any ideas where to start?
Thanks!
Edit - here's dialog I had with the user that didn't bring to light any issues.
You were actually on the right track
in asking about the firewall, because
you are trying to identify something
that is different between me and you.
Here's some other potential
differences.
Maybe we aren't doing it the same way:
Do you use keyboard shortcuts (Ctrl-C,
Ctrl V) or the context menu (right
mouse click and select copy/paste)?
Maybe our computers are different:
What hardware (Windows/Mac), operating
system (XP, Vista, etc.), and browser
(IE, Firefox, etc.) are you using?
Maybe our understanding of the problem
is different: Do you not see the text
when you paste it in, or is it not
being saved?
Maybe what we are copying from is
different: I copied something from
Bugzilla and something from notepad.
Both are plain text. I need to try
formatted text, like from a PDF and
from Word. You need to try plain text.
This may be actually a user training issue. If it were me, I'd use something like crossloop to watch the user interact with the page. If you can see what they are actually doing (not what they SAY they are doing) then you have half a chance at reproduction of the issue. Based on your description, it is very likely not an issue with the software, but a PEBKAC situation with your user.
Notes on Crossloop
We use crossloop with our clients and our developers in training. Basically you install the software (very easy) on both your computer and the end user's computer. The end user then authorizes you to "see" his machine by sending you a connection code. Once connected, both you and the user can move the mouse/type/see the other person use the mouse.
It would be like a remote desktop or vnc session, but much easier to get up and running across firewalls and without too much setup/config headache.
It is also a free download, and a free service (the last time i used it anyway).
Suggested course of action
Install Crossloop on your machine and familiarize yourself with it. (maybe do a trial run connect with a co-worker)
Call user and ask if they would be willing to show their issue to you directly via some screen sharing software.
Walk them through the install and connect of Crossloop.
Instruct them to show you the issue.
Watch for glaring errors, etc.
Hopefully see either what the user is doing wrong, or what conditions the bug manifests itself.
