Diagonal gray lines

useppewind

I have a table loaded via Ajax with 180 columns and 5300 rows. The text in the cells is 0-20 characters long. It has a scroller, fixed columns, search builder, bootstrap, no paging enabled, buttons, and export. Is it normal that while I scroll the table with filters active, diagonal gray lines appear? If I scroll further down or up, the datatables recovers a bit, but then it comes back; it's annoying.

If you have Scroller enabled, then yes. See this example.

The lines are shown when the rows haven't been drawn for the virtual location of the scroll at the time. You are more likely to see them if you have server-side processing enabled (I'm not sure if you do or not).

You could try disabling Scroller and see what the performance is like without it.

I'd suggest also reading over this blog post for a description on how Scroller works.
