Hi all,
opening a designer from an Ignition 8.1.45 gateway I've been asked to share my monitor (I'm on Ubuntu 24.04) and an icon appears from time to time on the activity bar like the following
Any idea?
Thanks in advance, regards
The Synthetica look and feel has some goofy fallback code path that uses java.awt.Robot in the course of rendering shadows or opacity or something for popup menus.
You might be able to disable it in a startup script or something.
from javax.swing import UIManager
UIManager.put("Synthetica.popupRobot.enabled", False)

On a KDE Wayland session a screen sharing dialog pops up continually any time you try to access a menu item, and choosing the output to share does not seem to have any effect or "stick", preventing access to the menu.
As a workaround, the Designer can be started with -Dawt.robot.screenshotMethod=x11, which will simply cause the screen sharing attempt to fail rather than invoke this new dbus sharing request code path that doesn't seem to work on KDE.

Interesting, noted. (I don't use Wayland--it's fairly new multi-monitor support doesn't play well with KDE.)
Does this mean that it's the Synthetica components calling java.awt.robot that triggers the request, despite nobody actually requesting a screen shot?
Weird, but thanks for looking into this for us.
Yes, it does it in the course of trying to render a shadow on the popup menu or something.
I experienced the same issue on 8.1.47.
Adding the JVM argument -Dawt.robot.screenshotMethod=x11 as Kevin said works for the time being, but there are some minor issues. the shadows on UI elements appear black, and drop-down menus appear in unpredictable places.
I have multiple monitors, and sometimes opened dropdowns appear on a different monitor from where I have Ignition Designer open.

8.1.48 is going to support -Dignition.synthetica.customXml=... system property that you can point towards a synthetica XML file, such as one containing this:
<synth>
<defaultsProperty key="Synthetica.popupRobot.enabled" type="boolean" value="false"/>
</synth>
which can be used to set the Synthetica.popupRobot.enabled property, as well as any other Synthetica UIManager property.
I'm not sure if the popup menus appearing in random places are related to this or not.
I am still getting a screen share request, I have created a xml file /home//synthetica.xml with the contents from xml section in the documentation and the JVM Arguments under settings>Designer Defaults "-Dignition.synthetica.customXml=/home/synthetica.xml" (quotes for clarity, and excluded from the field).
Attempting any action that would create a context menu or attempting to expand any menu bar pops up the screen share dialog.
Ignition design launcher version is 8.1.48 downloaded from the server running 8.1.48.
I have also tried the -Dawt.robot.screenshotMethod=x11 option, with the same results.
Are there any known issues with this option currently or am I potentially running into another issue?
If setting this param to x11 also didn't work then maybe there's an issue with the way you're trying to configure/pass these params all together and they aren't being picked up.
Screenshot of launcher config maybe?
edit: fwiw, in my most recent interaction with this (latest KDE at the time), the share permission thing still popped up, but it actually saved my choice and let me continue after that. I think. Unfortunately I no longer have quick and easy access to Fedora/KDE env to try anything out.

I used the same method for the x11 parameter, I just completely replace the custom xml line with the -Dawt.robot line.
I'm hoping someone can point out where I'm just missing something obvious, but it may be my system.
Instead of defining it on the defaults, define it on the existing entry if you have one. I think when you define it on the defaults like that it's only for new targets you add to the launcher.

My hopes were fulfilled! Yes, it was the configuration for the entry. I thought it applied to all existing entries, but you hit the nail on the head.
Everything mentioned in this post worked for me in a wayland session. However I ran into another problem. When I try to access property browser tree or open a popup text editor, the popup closes immediately. Any ideas on what this could be?
