System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Intel(R) UHD Graphics Intel 4.5.0 - Build 27.20.100.8681

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-08-17 21:54, hash: 24c16f5457
Worked: 2.93.2

Short description of error
Trying to change the value of shapekeys or shader sliders with my stylus doesn't get detected the first few seconds, then picks up, but in a non responsive way. Also while using my stylus, if I navigate to a nested menu like say "Object > Transform" There's a Lag when moving to another option in the "Object" Menu.

Exact steps for others to reproduce the error
The steps above should apply. I did notice though, that if I change my Tablet API from 'Automatic' to 'wintab' in the the input preferences, it helps, but its still not as responsive as it is in 2.93

All these issues though, were non existent, if I tried using my laptop's trackpad. Also, my tablet is a Wacom Intuous Touch 5 with a stylus that supports up to 2048 levels if pressure sensitivity and has tilt support, just incase it could be any of these causing the issue.

Thanks.

This is likely due to getting flooded with input from Wintab.

To triage this we need to check if sliders/nested menus register to receive in-between mouse movement (they shouldn't). If not then the issue might be that Wintab sends redundant input, thus causing redundant frame updates.

This issue, mainly shows up, when the tablet input type is set to Automatic. Manually choosing Wintab actually helps, and that been for default for a while now.

When tablet API is set to Automatic it should be using Wintab when it's available, so the two should be identical.

As a quick test, could you set the API to Automatic, then hold ctrl while the pen is in range and report back whether a ctrl bubble pops up like this:

No bubble pops up when I hold Ctrl.

This pop up though, I do get on occasions when the driver bugs out, and I have to restart the service.

Assume the same is true here.
