Unfortunately, I can't interpret your screeshot because I don't know anything about karabiners.
The regular typing is not disturbed. Not if you mean an incorrect order of letters. "Space" is typed when the key is released. And "Space" is not typed when the key is pressed and held. Problems arise when a key should or should not do something after or during a certain time.
By the way, "Space" is just an example. It also works with any other key.
But the letters are much more important. Here, too, the same thing always happens. All letters are typed with a delay when the key is pressed. Not if a certain key was tapped before or after. There is no condition.
Of course, you pay a price for this. Writing appears on the screen with a slight delay.
It would be completely safe if all keys were typed when released. But then the visible delay on the screen is very annoying.
