I noticed that if i press "Strg" (which is in my case "FN" since i swapped these) it stops flickering for some time and just lights. Generally it seems to react to keyboard "usage".
@zaclab: The beep could come from pressing too many keys at once.

Yes it is that kind of a beep exactly but I was not pressing too many keys at once, just typing normally.
Weird stuff. What a shame because otherwise it is such a lovely machine.

For those wondering what this looks like, including what happens when the Fn key is pressed. The flickering resumes more or less immediately once you begin typing again.

Actually, I'll expand upon this: I have basically every single behavior described on this thread.
Lenovo support is mostly useless. Hardware claims that problems are drivers and send you to software, software people say that they don't support drivers or BIOS if you haven't bought the extra professional services warranty. The only time anyone has been useful has been one of the other threads (https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Yoga-3rd-gen-CPU-frequency-pegged-at-max/m...) when someone from Lenovo finally was able to reproduce and brought it to the attention of engineering.

Same issue as most people here. Received my X1 Yoga 3rd Gen today, immediately updated the BIOS because it seems like the correct thing to do. I didn't use the laptop before updating the BIOS, so I can't say if the flickering would have been there before. But I definitely now see flickering with any keyboard activity, that persists until I hold down a key, at which point the lights stop flickering. Seems like the BIOS update is the culprit. No beeping or screen backlight flickering, however. Thanks to those in this thread that brought it to engineering's attention. I'll do the same tomorrow.

Linked the thread to the Lenovo Twitter Support and they said they'll forward it to the appropiate team. https://twitter.com/LenovoSupport/status/983689718121582592
Got the same problem with the keyboard backlight flickering after waking up from Modern Standby. Sometimes the Touchpad and/or Keyboard don't work temporarily too.

I just got my X1Y3 yesterday and updated the BIOS to version 1.11. Still the same problem with the keyboard light flickering... Lenovo please fix this. It's really annoying not to have a litt up keyboard when working in the dark.
Also I experienced some problems with the touch screen not reacting at times... A restart resolves that temporarily.

I have the same exact problem with the keyboard flicker on my X1 Yoga (20LD). It started with BIOS update 1.10, it has NOT been fixed with BIOS update 1.11. There have been no other software or hardware changes to the device. It happens every time I wake the laptop from sleep, I can temporarily stop it by hitting Fn + Spacebar, but it comes back randomly (within the same active cycle). Rebooting seems to fix it sometimes, but not always.
Since the BIOS update, I also have the occasional keyboard problem where the keyboard doesn't seem to work at all. It hasn't happened enough times for me to be able to reproduce it reliably, but it has happened. Closing the lid and re-opening fixes it usually, it seems.
There is also a pointer drift that I sometimes see and the touchpad doesn't work during those times. Neither does the nub point/stick. Again, have to close the lid and re-open it to get it re-enabled.
The fingerprint scanner sucks badly too. But that has sucked since the beginning. It doesn't recognize me half of the time.
I bought one of the first X1 Yogas, the 20LD at that. I don't know what I spent $2500 on, because it sure as hell wasn't reliable hardware. Very, very disappointed.
