Yes, Intel is aware of the issue and have reproduced it themselves. The BIOS team is looking at it. Fix should be in next BIOS release.
For the screen flickering issue, a user reported that they found that the refresh rate was set to a wonky value. Make sure that it is set correctly for your monitor.
Hope this helps,
I have the same problem, I recently noticed the speed down of usb 3.0.
The worst thing is that I have an external hard drive with blue light if it acts in 3.0 and white light if it is 2.0
In another pc when connecting it turns blue and white in the nuc, so in nuc it acts as 2.0

Thanks for looking into it. That flickering was more like a short split second (very heavy) tearing, like when you have vsync disabled during a game and part of the screen gets distorted. So after the problems appeared i switched from 60Hz to 50Hz with the HDMI connection. That solved the issue for me. Video with my dvb-c stick looked smoother also, since im getting 25/50 fps content here in Germany. So i think i will stick with the 50Hz. But as i write this i switched back to 60Hz with the new "0045" firmware. No screen glitches so far at 60Hz.
But the bigger issue: >>> SLOW USB 3.0 ports <<<
The USB 3.0 ports still only work at 2.0 speed. No more then 38 MB/sec. Even with the latest 0045 update. That has to be fixed. My blue light indicator on my external 3.0 devices are off, meaning USB 3.0 is not enabled for them. I hope this issue is seen as rather urgent for the BIOS team.
Best holiday wishes ,
The USB issue is being worked as we speak and the fix will be included in a subsequent BIOS update.
