[joe] terminal falling apart sometimes when edititing file over ssh connection

[Fourhundred T. <400...@gm...>]

Hello,

when I ssh into another machine and edit file with joe, sometimes my
terminal is falling apart. This does not happen every time, and I am not
able to reliably reproduce it, but I have made few observations:

  1) it only happens when editing files via ssh, not locally
  2) it happens after I user PageDown or Pageup to scroll
  3) it only happens when -linums is enabled

Here are two screenshots of the same file. First shows the problem:

the second shows correct state:

what could be the problem here?

I am using joe 4.6-1+b1 on Debian 10.
