I'm mostly worried that the voltage multiplier is weak and it's not delivering even voltage across the sweep. Though I don't know if that wouldn't also effect the geometry? There doesn't appear to be any geometric distortion matching up with the brightness halo.
I cannot imagine that, the "tripler" furnishes the requested final voltage only at flyback pulses (last diode blocks from sweeping time), and CRT cap ("aquadag"+glass) holds it for a line time.

And is pretty rare to a CRT having a dim lateral zone (normally are the borders or, more rarely, in the center).
