System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 960/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2021-01-03 01:04, hash: 1e8f266591
Worked: 2.8 (i recently came back to using blender, it worked correctly back then though)

Short description of error
There is something like quarter of a second lag before the push and drag tools snap into correct position when using stylus.
Doesn't happen with mouse.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
Can be done with blank file and any Grease Pencil stroke scribble.... the more strokes the more it seems noticeable.

make a new blender project file or use preexisting one.
make a new grease pencil object
scribble something onto the canvas
go into sculpt mode
use push or drag and try to move the strokes (must use graphic tablet stylus, doesn't happen with mouse)

@The_Zadek could you repeat the bug in this build, copy the system console to this link, and link the paste in a reply to this report?

Here is the output of the window console as requested: https://developer.blender.org/P1876

I noticed some additional things, it's not a delay at all, i think time is not component of the bug, instead there is some sort of threshold which when broken, makes the cursor snap to the position of the stylus but before that, the cursor is unresponsive.
