Hello,
I've come across a problem with specifically screen with the switches -d -m.
The switches seem to cause the CPU usage to sit at around 100% single core
usage for the server and just over 50% usage for screen itself. Attaching
session also fails to pass keystrokes properly (keystrokes end up sending
outside of screen session for some reason?)
Issue seems to occur exclusively with BeamMP-Server (Multiplayer server for
BeamNG Drive, https://github.com/BeamMP/BeamMP-Server ).
screen ./BeamMP-Server <- no issues
screen -d -m ./BeamMP-Server <- High CPU usage
System Info:
Debian 12 (bookworm)
Kernel 6.1.0-20-amd64
Core2Duo E8400
