Plyxon Freezes After a Few Minutes on Ubuntu 25.10

After upgrading to Ubuntu 25.10, I noticed that Plyxon freezes after running for a few minutes. The application becomes unclickable; sometimes some menu items remain clickable but the rest of the interface does not respond. Unlike a typical unresponsive application, repeatedly clicking inside the app does not bring up the standard "Force Quit or Wait" dialog. However, the window’s close button still works correctly. This issue did not occur in previous versions of Ubuntu.
Logs are empty..
 
The bug is even stranger than I thought. It looks like everything is actually working under the hood. For example, I can blindly write a block of code that inserts something into the database and commits the transaction, then press F8. The code executes, even though nothing is displayed on the screen. So the program seems to be functioning "normally," but it doesn't refresh the UI.
 
We could not yet reproduce this on 25.10. Can you let me know approximately how long it takes before this happens, and whether there are any specific actions that need to be performed to make this happen?
 
I am observing the issue in order to find any patterns. I’m not sure if the error only occurs after switching windows using Alt + Tab. Sometimes the problem appears very quickly, within minutes after startup, while other times it takes a few hours. It seems that if the error occurs once, it tends to happen again soon after, which may suggest a correlation with a specific event.

Based on my observations, certain configurations that might be causing the issue are the nvidia-driver-580 as well as having virtualbox-7.2.2 running.

I will try to test with different drivers and without VirtualBox.
