Our customers have reported that the menu item background boxes do not clear in the JavaFX client being used (after a week or so of use) - see photo above.
If the menu items are clicked after this has occurred, they display and function properly, however the background boxes stay and will not clear.
We have reproduced this using a soak test (using xdotool to simulate repeated mouse use), but there appear to be no errors reported in the log files.
We have also ran this soak test using a Java 7 version and this behaviour does NOT occur.
The menu should look like this in normal behaviour:
We are using the latest version of Java 8.
Any ideas welcome, thank you.

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.
The website of PageSpeed Insight is the only place, where i get CLS issue in both of field and lab data.
Any other Lighthouse instance (by WPT, as API or by DevTools) displays CLS issue only in field data, not in the lab.
How can i diagnose correctly, which elements are causing CLS? Example.
PS: My question has the following cause: analyzing other websites i usually have under devtools → performance red diamonds layout shift, which, if clicked, display in tab Summary some data about this layout shift. Like on the screenshot:
But on the example site i get CLS diagnosted, but not displayed.
The synthetic (lab) tests only load the page (they do not interact with it), whereas field data is until page unload.
Immediately I can see one Layout shift is when you open either of the drop down menus, your scroll bars disappear (due to adding the class .overlayed) and the whole page shifts around. Synthetic tests do not open the menu so will never capture it, however this shouldn't actually contribute to CLS as it requires interaction to open (just something to fix).
The other thing I noticed is the bottom right corner icons cause a layout shift when you scroll and they collapse / open (the floating icons). This is likely to be the cause of CLS as it isn't via direct interaction. Scrolling does not count as user interaction when it comes to CLS.
My guess is that this is the one that gets found by synthetic tests sometimes and not others.
Finding Layout Shifts
In order to find layout shifts you can open developer tools, go to rendering panel (you may need to open it with "more tools") and click "Layout Shift Regions" so it is selected.
Now use the site and you will get a blue box around anything that shifts.
Or you could use performance traces
The other way is to run a performance trace in the performance tab and then just use the site. Once you are done complete the trace and it will tell you if a layout shift occurred and what item caused it.
Tracking them in the field
In order to capture layout shifts in the field yourself you should use something like Google Web Vitals library along with click / mouse position tracking etc and pipe it to your own backend or Google Analytics for analysis.
This lets you find issues with the page a lot more quickly and easily using Real User Metrics (RUM) data in real-time.
I'm in Xcode 6.2 Beta 3 (Build 6C101), I've added a menu and two menu items to my Interface Controller, and created IBActions for both. I've given them titles and images, but when I run the app nothing displays.
I've read
https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/WatchKitProgrammingGuide/Menus.html
and can't see anything about need to show menu items programatically - what am I missing?
You do not need to present the menu programmatically. The only thing you need to do is wire each button to IBActions in your Watch app extension.
The most likely issue is caching of the previous Watch app storyboard. Do a clean build and try again.
Finally, as you likely know WatchKit menus only display on a "force press". They cannot be used for the main interface of the Watch app. In the Simulator, a click and hold with the mouse will simulate a force press, and the animation will make it clear when you have done one, even in contexts where it doesn't do anything.
This was solution for me- Go to Hardware->Touch Pressure->Deep Press then try tap on watch simulator.
I have recently encountered this issue on a real device, although the menu was working as expected on the watch simulator. In my case, the problem was in SF Symbol that I've used as an image.
Everything was fixed after replacing it with an image from the assets catalogue.
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.
