Hi,
we have implemented virtualized scrolling in KendoReact grid and debouncing based on this sample: https://www.telerik.com/kendo-react-ui/components/grid/scroll-modes/virtual/#toc-debouncing-pagechange-events
Everything works ok in Chrome, but in IE11, there are multiple performance issues (i.e. scrolling is not smooth an even with 100 - 200 rows, it takes a second or two to scroll the grid down). As a first step, I tried to open the sample I linked above in IE to see whether the performance is poor in there as well, but it does not work (see attachment). I am also not able to open the sample in StackBlitz, since clicking the StackBlitz link does not do anything.
Could you please provide us with a working sample illustrating the virtualized scrolling with debouncing in IE11 so that we can see whether the performance issue is caused by our faulty implementation, or is a problem in grid itself?
Thanks!

Hello, Nikola.
Thank you for the details.
The example is not running on stackblitz as their editor platform is not working on IE 11.
This link can be used to run the example in IE 11:
https://react-v1gu5f.stackblitz.io/
I tested it and it was working as expected on my end and is just a little slower than in Chrome, but this is expected as Interner Explorer 11 handles the DOM manipulations slower.
Also, please test the real application when built for production as React is times faster in production:

Let me know if you need additional information on this matter.
