Hi Mychess,

It is difficult for me to find the reason of flickering leds : on my laptop, this flickering doesn't exist.
Perhaps always with your Nec Multisync 3D from 1990, at 30 Hz

"Nec Multisync 3D from 1990"? No, I've also a (not so old) notebook - I rather guess your laptop screen is too slow to see the flickering LEDs.

The flickering is definitely there, you're just switching on and off all the LEDs far too often in your drivers (the same problem already happened with your previous starchess driver)!
Regards,
Franz
