Hi, Tom,

Thank you for the provided details.

This problem has been discussed more extensively in the following forum thread:

https://www.telerik.com/forums/grid-with-remote-virtual-scrolling-fires-mutiple-read-requests-when-scrolling-fast#3389212 

As it has been explained by my colleagues, this behavior is by design. The only workaround is to turn off the prefetching of data, however the downside is that the Grid might appear a bit "laggy" while scrolling.

Workaround:

kendo.ui.VirtualScrollable.fn.options.prefetch = false;
 
$("#grid").kendoGrid({
    scrollable: {
        virtual: true
    }
});

Dojo:
