scrubbysliderOver the past year or so I have noticed an issue with using scrubby sliders when using Wacom pens in Windows 10. Trying to drag a scrubby slider will result in the pointer snapping back where it started depending on how much you move the scrubby slider. This behavior is very annoying and causes one to switch to the mouse or type in the values needed. Either way it slows down the workflow when using a pen.

This appears to be linked to the change in Wacom drivers to using the native Windows Ink function. Disabling windows Ink in the Wacom settings will fix it but it will break pressure sensitivity. There is a fix out there that tells Photoshop to use the older WinTab api that provides pressure selectivity and fixes the scrubby slider issue. The fix is detailed below and the full thread at the Adobe forums can be found in this thread: https://forums.adobe.com/message/8663212#8663212

Fix

1. Create a file that contains instructions to revert to the WinTab functionality.

2. Create a text file in a text editor such as Notepad.

Type in the following lines:

# Use WinTab

UseSystemStylus 0

3. Save the file as a plain text file named PSUserConfig.txt

4. Put (copy) the file into the Photoshop settings folder: C:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Photoshop CC 2015\Adobe Photoshop CC 2015 Settings\

5. Restart Photoshop and check the pen pressure and overall performance.

It may result in some pen lag (didn’t for me) but otherwise it fixes this issue.
