Horizontal scroll freezes even with 7 tasks, but browser scroll test shows 120 FPS

[no-inspi]

Hi guys, i have a very surprising behavior when adding svar gantt to my nextjs (v15.3.2) and react 19 (v19.1.1).
I added a very simple svar gantt with 7 tasks mock data.
The gantt is freezing very hard and it's likely impossible to use it ...

I got this error when trying hard to scroll :
Maximum update depth exceeded. This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render.

To be sure it comes from svar, I tested with a very simple component and added a check for browser scroll.

Thanks in advance for your help

Hello @no-inspi ,

I tried to reproduce the issue you described but was unable to encounter the same freezing behavior.
To assist you further, I’ve created a simple example that you can review and test in your environment: https://stackblitz.com/edit/stackblitz-starters-d1shp5ba?file=app%2FGanttComponent.jsx

Please check the example and see if it behaves differently in your setup.
