example app crashes horribly

[epsilonhalbe]

OS: MacOS BigSur 11.6
Terminal: iTerm/Kitty

steps to reproduce:

small terminal

git clone https://github.com/Tenchi2xh/Scurses && cd Scurses
sbt onions/run
after the sbt start the following is printed, but the process then hangs and I need to kill it by sending SIGTERM

if I use a bigger terminal output is refreshing every second or so and wiping the screen blinking ocasionally

changing the terminal size crashes the application.
