Angular Scheduler: Slow Scrolling on Resource Headers with Firefox

Asked by Alexandre Menif
2 years ago.


We are using the Angular version of the scheduler in our project and we have noticed that scrolling on the resource headers is very slow compared to scrolling on the event area.

This issue only appears on Firefox, we did not reproduce it with Chrome (but we do not know for other browsers).

This issue can easily be reproduced on the demo "Angular Scheduler: Loading 400,000 Events" (

I also attach a short screencast where I am reproducing the issue on the demo.

Is there anything we could do to fix this problem on our side?

Thank you for your help.
