Hello,
I have split my dhtmlx grid like
grid.splitAt(10)
when I render grid bottom row of first part is not rendering ,-issue
When I do scroll , some rows disappears , then I need to scroll little up/down to get them back.

I have enabled smartrendering
I have 20 as my preRendering size.
I have also tried setAwaitedRowHeight(29) for chrome
Nothings works for me

Please suggest the solution, some half blank rows seems very annoying Now.

Thanks,
