Probably due to leakage current through whatever is switching the driver on and 'off'.
It could also be dimming to off not working properly if that is what they are doing on the 320 driver.

I would guess they need to turn the plug around.
AC current has a zero and a phase wire. If the timer is breaking the zero wire then the phase is still hitting the driver. I've seen this flickering effect caused on fluorescent tubes myself.
Make sure the phase wire gets interrupted. Preferably by using relais with double pole switching or otherwise making sure that the plug is in the "correct way". You can test this with those screwdrivers that light up when you stick them in the socket.

I bat it tho thin wire in it hating the system up or heating up and noticing it the driver is. I had a problem we're I had one batch a that of 6 of them and the driver could power 7 chips but the 6th chipped was bad so I had to unhook every check power than mom 1 by one and found out one check was bad

Current leak through the timer?
I had this happen on some Meanwell LPF drivers running XP-Es just plugged into a standard light timer. When I put the circuit on an actual breaker, the issue was resolved.

how is it grounded? floating ground

Ground leakage? He might have a plug somewhere on the same circuit wired backwards.
two different wires, which are bonded.
Bonded at the switchboard/panel for a reason.two different wires, which are bonded.
