Touch Bar flickering CONSTANTLY; Resetting SMC does nothing

2017 MacBook Pro, T-1 chip. Touch Bar flickers and blinks constantly. Resetting the SMC as suggested in numerous other threads does absolutely nothing. Makes using the bar EXTREMELY difficult/impossible.

What else can be done besides resetting the SMC? This is my only laptop, and I have to use it for work, so I can’t leave it at the Genius Bar for indeterminate amounts of time. If that’s the only suggestion, save your digital breath—I’ll just begrudgingly live with it until I have to cough up thousands of dollars for another one.

Lastly, I’m not a baby-boomer ;-P, ergo I’ve already been through basic troubleshooting steps. SO, PLEASE DON’T REPLY WITH THE ROUTINE TECH-SUPPORT LITANY OF THE OBVIOUS. MY OS IS UP TO DATE. MY POWER SOURCE IS MINT. I’VE SHUT DOWN/REBOOTED.
