Short description of error
On my Wacom Intuos,
middle mouse button does not work in Windows Ink but(edit: mmb was driver bug) pressure seems does not work on WinTab.Windows Ink works on 2.93.4. And the issue still happen even when using a fresh install.
I recorded the issue to show what happens and the difference on my system between the two.
Exact steps for others to reproduce the error
1. MMB Issue:Use Wintab and move around the viewport with the pen button set to middle mouseCompare to Windows Ink (can't use)The issue still happens with a clean install.

@Ravenman13, thanks for the report.
@PrototypeNM1, can you replicate the problem?
Any idea what might be causing it?
@Ravenman13 Could you test the following.
@mano-wii There's a Wintab fallback case when it and Win32 disagree on the cursor position. I'll have to add logs to verify.
I've seem to have fixed the issue with Windows Ink. I rolled back my Wacom driver to (6.3.43-3) instead of the lasted driver and that seems to have fixed the issue.
I'll try reinstalling the driver and see if that's the issue on my end.
Wintab is still has issues with pen pressure, WIndows Ink is fixed.
@PrototypeNM1 @mano-wii
The issue I've found seems to be with the latest Wacom Driver (6.3.44-1).
On a separate system I installed a one driver version back (6.3.43-3) and middle mouse worked on Windows Ink.
I then installed the latest driver and middle mouse didn't work.
So from what I've found it seemed to be a driver issue.
Is pressure still an issue in Wintab (I would assume it's an issue with both drivers)?
If so could you open the Wacom Tablet Preference File Utility, Backup (just to be safe) and then Remove under All User Preferences, then test whether pressure works?
@PrototypeNM1
I've tried what you suggested and still the same issue, maybe this issue is unique to Wacom.
@Ravenman13 can you run [this build ]], paste the console log [ https:*developer.blender.org/paste/edit/form/default/ | at this link, and copy the resulting link here?

Hi! I don't think this is a Wacom related bug. I have been having the same problem with the latest 3.0 alphas on my Surface Pro 7 using Windows Ink.
Works as expected on previous Blender version (2.92 at least).
EDITED: Sorry!!! My above statement is false. All is fine on my Surface Pro. I did have issues yesterday on my Wacom Studio Pro but they seem to have been solved by switching input from Wintab to Windows Ink and back to Wintab. I'll try to investigate further. Sorry again for the confusion...
@Pyer If you figure out the issue go ahead and open a new bug report and tag me. Tablets often have similar sounding bugs with different causes.

@PrototypeNM1
The Wintab High Frequency Logging build fixes the pen pressure issue I noticed on Wintab.
I also noticed that on 2 different systems with the same tablet that the pen pressure on Wintab did jump at times where it felt like the sensitivity went higher then I felt pressing, doing quick brush strokes.
The middle mouse bug on the lasted Wacom drivers was still there when using Windows Ink but I could still use middle button for navigation on WinTab.
Here's the console Log:
https://developer.blender.org/P2374
@Ravenman13 could you try this build?
Self triaging note: this tests whether modifying the Wintab context to force mask all buttons fixes the issue.

@nicholas-14 Rishel (nicholas_rishel)
On the build you posted Wintab still has the same issues. I appiled the Wintab and restarted Blender and still no pressure sensitivity on Wintab.
I also found when that Krita was set to Wintab instead for Windows Ink when I looked at the preferences.

The symptoms of this issue should be resolved by
60c0b79256
, but there remains an underlying issue that needs further investigation. Lack of pen pressure was an indicator that Wintab was falling back to low frequency input, which can result in jagged lines when drawing.Changed status from 'Confirmed' to: 'Needs User Info'
@Ravenman13 could you repeat the bug by running
blender.exe --debug-wintab
with this build, copy the system console to this link, and link the paste in a reply to this report?Just a note: this bug report doesn't happen in the main release of Blender because of fallback that is hiding it. We'd still like to fix this properly because the fallback causes jagged lines when drawing.

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.
Thanks again for the report. If the problem persists please open a new report with the required information.
