Hello,
I’m using a GroupDescriptor and have disabled LoadGroupsOnDemand for data sets under 100 records. I’ve noticed a bug where, on first render, all rows appear ungrouped for a brief moment, then “jump” into their correct groups a split-second later.

When I add a debounce to the OnRead event, the issue disappears, which suggests a correlation between a heavily loaded OnRead handler and the delayed grouping.

What could be causing this behavior, and has anyone encountered something similar?

Hi Mateusz, I don't observe the described behavior on this test page: https://blazorrepl.telerik.com/wzkKFgvP05cGtzZg06

Can you show what is different in your Grid setup
