[SOLVED] Beta 4.9.3.0 - "^E" being written on SSH while a long-time command is running

On SSH sessions, I see these strings being written to my terminal while there is a long-time command running:

They're written once every 30 seconds, as you can see on the attached video.


When no command is running, these strings aren't automatically written. The focus is set on another window than RDM, so I'm sure this is not me sending some keystrokes involuntarily.

I didn't have this issue with v4.6.0.0.
