This will not fix the problem but may help with diagnosis if there is
a video camera synchronization issue. Fiddle with the trigger A
holdoff control which is located toward the bottom right. Holdoff is
used to increase the time after a sweep before the next trigger will
be accepted.
I would still check the power supply voltages and ripple before
getting too involved with looking for other causes of the problem.

I noticed that and wonder if the relatively low video camera frame
rate is disguising what is really going on.

I would open it up and check the power supplies for voltage and ripple per the manual. It seems to be jumping sync at a periodic rate.
