I've recently run into an issue when running my app that when I hover over items in the drop down menu, all of the items get highlighted but I'm not able to actually select anything when I click on it. The highlighting goes away when I move my mouse away from the menu, so it might be some kind of graphical issue but unsure how to troubleshoot. I'm running this on Ubuntu 24.04.1 LTS and with Matlab version 2024a. Has anyone else run into this issue or know how to resolve this issue?

What if you create a new, mini-app with just the one control...does it work? If so, then it's something inside the other app; if not, then the idea of it being related to OS or graphics internals has merit...begin by trying to at least narrow down the possibilities...

Hi Joseph,
I understand you are facing an issue with the dropdowns in the App designer R2024a in Ubuntu 24.04.1 LTS.
To regain control over the dropdown, kindly follow the below workarounds to resolve the issue:
  • Try running the following command in the terminal prior to starting MATLAB:
$~ export ENABLE_QWEBWINDOW=true
  • Change the window focus mode to "click" instead of "mouse" in the settings.
Kindly refer to the following Bug report to know more about the above workarounds:

I hope this helps!
