I have a new L390 running windows 10 using the latest chrome browser.
Everything is fine so far, but when using Google Meet (https://meet.google.com/) I experience a terrible keyboard lag. That means typed letters would show up with a high delay. Often I stop typing and new letters are still being "processed" on the screen.
Does anybody experience something similar? Is there a solution?

I was trying to figure out what is going on.
First I tried Ubuntu 18.10 with google meet and it worked without problems and keyboard lag.
Back to windows I realized that using just the Windows Camera app would also not cause any keyboard lag. However using the voice recorder resulted in the same keyboard lag as described in the initial post.
My next attempt was to use google hangouts but with my bluetooth headset and the integrated bluetooth microphone. The result: No keyboard lag at all. Selecting again the built in microphone "Default: Microphone Array (Realtek Audio)" as the input brought back the keyboard lag immediatly.
What is going on? Help is much appreciated.

My L390 that I us at Thailand also have keyboard lag/slow issue when I use any s/w with Microphone input.
Including active Cotona with feature always listen "Hey Cortona", the key boar will lag/slow all the time.
When I de-active "Hey Cortona", key board resume to normally speed.
But when I plug 3.5 port Headphone, and use with Sky, keyboard is lag/slow again.
It's really bad and I very dispoint "Thinkpad"
I think there is something wrong or bug on the BIOS
@adminLenovo, please read and execute

guys the drivers by realtek are awful now. do not install them if you do nto want lag.
ex you have lag when you plug in a headphone and remove it quickly. do that while a video is playing and you hear the sound is cut off for 5 seconds
so you remove the realtek driver and let the driver by microsoft do the job.

I switched to Ubuntu a long time ago, where the problem does not appear. I have a dual boot setup and I just checked again in Windows and the problem persists. I tried to to change the audio driver, but it didn't really work.
I can't believe that Lenovo doesn't care about this problem. Drivers or firmware should be fixed by now! Or are just a few units affected by this problem?
