Incorrect rendering in Konsole and Cockpit Terminal in Rocky Linux 8

[fxvazquez]

Describe the bug
The text user interface is not correctly rendered in terminal emulator like Konsole (KDE) or the web console in Cockpit. It's working ok in RXVT for example. Tried in v0.2.2.
Fails on rocky linux 8.4.
Works ok on Ubuntu or Centos 7.

To Reproduce
Run drbdtop in Konsole or Cockpit in Rocky Linux (probably in RHEL 8 al well).

Expected behavior
The TUI should be rendered OK, like in other terminal emulators.

Screenshots
Example in Konsole:

Example in Cockpit:

confirm the problem on Centos8 Stream

Please try
export TERM=xterm
and let us know whether the problem persists.

It seems that the output is messed up with TERM being set to xterm-256color, which seems to be the default on those distributions.

I can confirm this is working on AlmaLinux 8 👍
