I think there is a bug on Gantt widget that occurs depending either on screen size/resolution or chrome zoom level.
I got bug reported on my module which uses gantt widget. Client reported that on some of their screens rows on the left side are misaligned with rows on timeline.
After investigation, I managed to reproduce issue by scaling zoom on Chrome, to 90%. (they have bigger and probably better screens than mine, so it wasn't shown on my system).
Same issue is reproducible on https://demos.telerik.com/kendo-ui/gantt/resources, if you resize gantt zoom to 90%. (I also attached image from demo)
I also looked though to find possible solution, and it seems that if we replace current fixed font-size: 14px, with font-size:1.5vh it seems to scale correctly.
Please could you take a look and suggest solution (I would prefer to avoid overriding native css of the widget).
Thank you and best regards,
