Ubuntu 22.04  
Xojo 2024r3

Okay, I’ve identified a pattern: when the TabPanel’s .left and .top properties are not set to 0, the Listbox content shifts proportionally based on the margins of the Listbox and TabPanel.

Is there a workaround to prevent or correct this offset?

I’ve included a project with a Slider to demonstrate the issue.
