I'm not really sure what you're expecting. Of course the phase
alignement between the Tx and Rx is going to be random depending on
restart.
Using the same clock will prevent it from drifting, but the initial
phase alignement is random. This is usually resolved by using training
sequence, headers, differential encoding, ...
I had the same thought -- it looks like a phase change. This is a PSK
signal, right? Have you looked at the constellation diagram?

Neither synthesizer will start with any particular phase offset, either.
