Hi Martin,

thank you for the detailed troubleshooting instructions.

This problem occurs with both Bash 5.0.17 (Ubuntu) and 5.2.21 (Debian)

I'm currently not able to test with other versions of readline.

These artifacts can be seen using the aforementioned versions of Bash 
inside xterm 353 and gnome-terminal 3.36.2.

For all four combinations:

term=xterm-256color
right-auto-margin=enabled
left-auto-margin=disabled
semi-auto-margin=disabled

I haven't found a way to discover that for gnome-terminal.

For xterm, before and after observing this issue:

* Enable Auto Wraparound: true
* Enable Reverse Wraparound: false
