I too have issues with keyboard input lag on Ubuntu 18.04. I've made sure I'm current on all updates, I'm using the US layout and my language is set to English.
In my case I am using a KeyMouse Track (which the OS recognizes as two separate keyboards) but I have confirmed that it isn't related to the keyboard devices - two Logitech G810 keyboards plugged in simultaneously exhibit the same behavior.
As others have described, there is significant lag when pressing keys from two keyboards in an alternating fashion, and the faster you press the keys, the longer the delay before anything shows up on-screen once you stop typing. If only keys from one device are pressed, there is no discernible lag even if both keyboards are still plugged in.
Hopefully we can get some traction on this. I don't think Wayland is a viable option for me as I have an nVidia graphics card and I also have to use Skype for work... and I don't really want to switch to Plasma either.
