After the Update to Firmware 140.0.0.0.0 i have graphic glitches

After much testing im really sure the firmware update is the source of the problem

Is there a solution to get back to the old MP51.007F.B03 firmware to test my theory?

Nvidia's drivers have had glitches and artifacts going back to well before that firmware update. It's unlikely backdating will resolve it.

I was on El Capitan with MP51.007F.B03 Firmware without glitches

After update the firmware to MP51_0089_00B (update needed for HS) and then to 140.0.0.0 i have glitches on exact the same El Capitan System.

TITAN problems? If so, it's not the firmware but the NVRAM.

The only way to downgrade a Mac Pro firmware after you flash 138.0.0.0.0/140.0.0.0 is reconstructing the BootROM.

BTW, I can reconstruct any firmware after the intermediate files are created.
