For vi, the issue seems to be visible only when scrolling to top:
!image-2024-06-06-18-13-06-244.png!
The cursor commit performs a set_columns which conflicts with the copy by
changing the operation_type.
For nano, the problem is not exactly the same: guacamole should process 'S' and
'T' CSI sequences (scroll up and down {*}by amount{*}).
Here you will find the pull request that fixes both of these issues:
