Ok. This isn't a full diagnosis but an observation.
That stepped output, when end of line just moves the cursor down one row
without returning to the start of the next one? That is a standard symptom of a
process _outside_ your tmux session producing output.
What's happening?
UNIX programmes end lines with newline (NL, ASCII code 10) characters. The
normal "cooked" terminal mode converts these into a CR (carriage return, moving
the cursor to the left edge) and a NL (moving the cursor down).
When you run a full screen programme like tmux or screen or vi, that mode gets
turned off and the programme itself is responsible for managing the display.
That allows it proper control. Tmux itself manages a pseudoterminal and the
terminal mode on _that_ inner terminal does the NL->CR,NL translation, so all
the inner programmes emit normal looking output.
_However_, programmes running _outside_ your tmux session are not having this
done because the outer terminal is not in that mode. Therefore the stepped
output is from a programme outside your tmux session.
What have you got which (a) connects to plus.google.com and/or (b) runs a GUI
(see the MESA-LOADER and libGL messages, an X11 3D rendering library). I
suspect a web browser started from the terminal outside the tmux session. Or a
messaging programme (and "SID" might be a "session id").
