I'm experiencing this problem as well. Affected versions 1.16.201 and 1.16.210 . Haven't tried anything newer (beta).
It is really strange, because mouse does not seem to be affected at all. Only keyboard. I can look around withe the mouse and always getting response immediately and correct behaviour. But with keyboard not.
This problem seems to be connected with the process priority. Just start some processort hungry process in the background, like Google Drive syncing large files or start rendering some h264 video with a video editor. Then it starts really ugly. Delay 10 seconds or even more. SPACE button not working as if completely.
In 1.16.201 it was enough to set gfx_vsync to 0 and the problem was gone for most cases.
Sometimes it helped to configure Windows toolbar to hide itself automatically. But this did not help always.
Recently I was forced to update to 1.16.210 and the setting gfx_vsync to 0 stopped helping.
I also tried to set max frame rate to 60 as recommended in some forums, but that did not help either.
Another notice that might be related to this. While I'm writing this text, I'm rendering h265 in background and I notice considerable lag even in this textarea box. Especialy when long pressing a key, like cursor to the right, it keeps going to the righ even after releasing it.
I wonder if this might be somehow connected. I remember that these PC keyboards have some key cache or something that remembers key strokes and they can be then read.. maybe it is more about the drivers behind keyboard and not the handling of keys in game at all. Mojang might add some kind of different handling of keyboards.
