I'm experiencing input lag on Ubuntu 20.04 with the R-Go Split Break Ergonomic Keyboard.
An amazon reviewer [1] points to the fact that this problem does not occur on all linux distributions. Is anyone using a linux distribution where this problem does not occur?
R-Go support suggested using wayland. This did not help.
