You might be surprised just how fast 80ms really is. Again I'm not saying this shouldn't be addressed if it's causing noticeable issues but labeling it as a bug just seems strange to me (but that label wouldn't change the priority for me by itself)
It's noticeable if something is moving because that won't look smooth. But a 80ms delay will be very hard to notice. An average reaction time is around 300ms.
With all the downvotes I'm getting I might be missing something though :P
