Why are my streamlines discontinuous as it crosses from a stationary frame of reference to a rotating frame of reference?

The variable “Velocity” is relative to the local frame of reference. If the frame of reference is rotating then it is relative to the rotating frame – so it will be different to the stationary frame by radius x omega. So when streamlines go from a stationary frame to a rotating frame the velocity jumps by radius x omega. To see continuous streamlines plot the variable “Velocity in stationary frame”. This is referenced to the stationary frame regardless of whether the frame is rotating or not, so will be continuous. You might need to access this variable using the puzzlingly labeled “…” button.
