jqGrid Cannot Handle More Than ~1.5M Rows with Dynamic Loading/Scroll

I've got a sample table I'm using to build a proof of concept using jqGrid 4.6.0.  The sample table contains ~45M rows (the production tables will routinely be 800M-1B and could reach 5-6B rows).  I am dynamically loading 500 records at a time via JSON using a variation of the sample PHP script provided by your example.

I can see that there are 90,000+ pages, and the record count (1 to 500 of 45,000,000) shows correctly.  Unfortunately, I cannot page beyond 1,525,000-1,526,000 records no matter what I do.  I suspect this has something to do with the height of the DIVs in pixels generated by jqGrid.  In this case, when inspecting the element, I see a div with a height of 994357144px.  If I change scroll: 1 to scroll: false, it works just fine via pagination.

Is there some way to overcome this?  Has anyone else tested with 5M, 10M, 50M records and found success?  I really like jqGrid otherwise, but the scroll is a must.

Unfortunately this is a limitation in the grid and depend on the browser.
In order to fix we need to rewrite the code for virtual scrolling, but I'm not sure that this will be done in the near future.

Kind Regards
