AI Summary: The user reports that the "dnb icon bop" animation behaves inconsistently across different frame rates; it appears correctly at lower FPS but is nearly nonexistent at higher FPS. This indicates the animation's speed or duration is inadvertently tied to the frame rate rather than a fixed time interval. The issue is observed on an older commit of version 1.48.1, and the user is building from source.

This setup is causing an error, and the user is seeking help to understand why their nested table approach isn't working as expected.
