Hi,
The described behavior is not expected. Could you please provide more information about the Grid configuration used on your side? Are the paging and virtualization enabled?
I would appreciate any details on how we can replicate the issue on our end. I will also recommend taking a look at the article linked here regarding Best Practices for improving performance in the Grid:

Looking forward to your reply.

Hi Glenn,
Thank you very much for sending the test page. I reviewed the initialization of the Grids on the page and I noticed that the pageSize of the Orders Grid is set to 2000 and of the Customers Grid is 10000. Please note, that pageSize should be limited to a smaller number. For example, please set the pageSize to 100 and test the behavior. You can also check the Virtual Scrolling aticle linked below:

Hi Glenn,
When the virtualization is enabled the data will be processed on chunks. For example when the virtualization is processed on the client, if the pageSize is set to 100, elements for the first 100 items will be rendered in the browser. Then, when scrolling elements for the next 100 elements will be rendered, and so on. However, in case the page size is set to a larger number such as 10000, then even initially there will be elements rendered for the first 10000 items of data in the Grid which will leads to performance issues.
I hope this helps.
