After leaving Kerbins atmosphere (+70km) you can use timewarp to separate both vehicles. Inside Kerbins atmosphere i was unable to succeed with timewarp to separate both vehicles.

I am able to launch the game from steam with "Proton Experimental" with the following system: OS: Kubuntu 22.04.2 LTS KERNEL: 5.15.0-60-generic CPU: AMD Ryzen 9 5900X 12-Core GPU: NVIDIA GeForce RTX 3080 GPU DRIVER: NVIDIA 525.78.01 RAM: 64 GB With the launch options provided by @Nemecle i am able to circumvent the PD launcher I experimented with the additional launch option "PROTON_USE_WINED3D=1" and on my system using the option produced a heavy drop in fps. Following some images with the launch option (fps counter in upper left corner): And now the same situations without the launch option (fps counter in upper left corner)

I am excited for the new UI, directly integrated better graphics and sounds, the animated kerbals, new better looking RUDs, and a linux port further down the road ;-)
