Worked: (newest version of Blender that worked as expected)

Short description of error
Pen pressure doesn't working in 2.91.0 with Huion Kamvas 13.
Well, It works sometime but most of the time NO.

I thought it's tablet's issue since I didn't have display tablet when I was working on 2.82, but it works fine in 2.82 version.
2.90 also doesn't work.
I tried to change Tablet API to windows ink, wintab, automatic but still no luck.

Exact steps for others to reproduce the error

Edited:
Fresh installed Blender 2.91.0
Window - New Main Window
Try to use sensitivity on strength or radius in New main window in Sculpt, Weight Paint, Texture Paint.
Here's video

I have one of those and I'm not having any problem with it in blender 2.91, tho the alpha version 2.92 broke pen displays in general and it is being worked on by @nicholas_rishel.

there is a task related to this problem in 2.92 if you want to check it out or test by yourself #82711.

Thanks for the the heads up. I read the thread and unfortunately there's nothing I can do.
Actually I managed to make it work today.
But the pen pressure is only working in original window.
In the New Main window, the pen pressure is not working. I think this is the issue here.
I updated my original post and linked the video to demonstrate this.

yep. it seems like blender stops grabbing the pen presure whenever you create a new window, mind taking a look @PrototypeNM1 ? :)

Quick sanity check, could you check that your drivers are updated?

Chanmin Lee commented

2020-12-25 02:04:11 +01:00

Do you mean the tablet's driver?
Yes it's up to date.

I've seen this behavior before in other tablets, they are probably based on the same broken driver. The problem is the driver does not deliver events to the correct window when a process has multiple windows. Additionally it doesn't seem to be delivering button events.

If you want to report the error to Huion, here's a blurb I sent to Veikk for the same bug, feel free to link to this bug report:

When a single process has multiple windows and a separate Wintab context per window, the tablet driver only sends updates to the most recently opened Wintab context. The driver recognizes when the application changes the overlap order and sends out WT_CTXOVERLAP CXS_OBSCURED and WT_CTXOVERLAP CXS_ONTOP to the correct windows, but continues sending all events only to the window with the most recently opened context.

Additionally relative button input does not seem to be working.

How tablets are handled was changed a lot between Blender 2.82 and 2.9, and more so in 2.92. These changes allow for high frequency tablet input for Windows Ink and Wintab. Unfortunately these changes exposed a bug in your tablet's driver.

Marking this issue as invalid as unfortunately it's a driver bug.
