Display errors, especially when scrolling

[jszym]

Hi,

Very cool project!

I'm experiencing some very bizarre errors in how a table is displayed. This (256mb) is the tab-delimited file in question (I decompressed it with gunzip before feeding to csvlens).

When I execute csvlens -d \t variant_summary.txt, this is what I see (on both kitty and GNOME terminal):

After pressing the down arrow 12 times, this is what it looks like:

And finally pressing the right arrow 3 times:

So, as you can see, there are a number of display issues here. Columns and rows aren't lining up properly, and the problem is exacerbated by scrolling.

Any ideas what is causing this?
