When connecting with --vnc only every second keystroke in terminal gets displayed

[appryst]

Heya, when I run a macos vm with tart run macos --vnc and connect with native screenshare, only every second keystroke is displayed in the Terminal.
For example if i type ls only one of the two letters is displayed until i press a third one.
Connecting over the tart application without --vnc works without that problem and when I screenshare to another non-tart-vm mac-device it works aswell.
It seems to be specific for the terminal aswell, as I dont have that problem when typing in Safari for example.
