Tablet Input Delay

[nettleflap 0]

OS: Windows 10 Home
Intel Core i7-7700K 4.20 GHz
16 GB Ram
NVIDIA GeForce GTX 1060 6 GB
Tablet: Wacom Intuos Pro PTH-651
Tried versions: 1.7.3.481 and 1.8.0.532 (Beta)

Issue: When I start drawing or painting, there is an initial delay of under half a second before what I draw appears. I have tried drawing with mouse, the issue is there, just a shorter delay.
I tried the tablet in MS Paint, no delay.

I tried to disable Windows Ink, still the same.

Here is a demonstration. You can see that it jumps from start to somewhere in middle,  then it works normal.
