Pen pressure glitch with some brushes

[Ross]

This issue seems to have resolved on my XP-Pen.

Windows 11.

TV paint 11.5.3 64 bits

Hi, I tried your brush on Win10 + Wacom Intuos Pro, without issue.

I don't get the bug when I use their brushes. I get it when I modify the eraser settings to be a hard eraser brush.

The first below picture is the default TVPaint "Eraser Brush" settings:




These are the changes I made:

In Power settings change "Pressure" to "Constant":



In the profile editor delete the slope to make it a hard brush:



From this:



To this:



It should look like this now:



The last change is in the Size settings. Change "Constant" to "Pressure":



Here is a video of me getting the eraser brush issue:

Can't replicate this issue in any other drawing/art/graphic based program besides this one. I tried Clip Studio, SAI, Photoshop, and many others

Things I tried:
• Updating drivers
• Reinstalling the driver
• Toggling Windows Ink in Wacom Tablet Properties
• I wanted to try pen calibration, but don't have the option available
• Changing the Tablet from "WinTab" to "Ink" in TVPaint's preferences, and toggled the "Windows Ink" option in Wacom Tablet Properties along with it to see if a combination works out.
• Using the latest version of TVPaint
• Tried using the eraser part of my tablet pen to see if happens there (it does). I generally don't use the eraser part of my pen

I want to clarify as well I CAN'T replicate this issue with the pen brush at all:



Only the eraser brush:



And I CAN create a custom pen brush using the eraser drawing mode, but the thing is now my brush sizes will be linked whenever I switch between the drawing modes. Not only that when I start swapping back and forth its gonna be resetting my brush size back to the size I made when I created the custom brush which is annoying.

UPDATE:

I've been able to replicate this easily by gently drawing on my tablet. Here is another video for reference:

I've been unable to replicate this in any other program. I'm pretty certain this is a bug with the eraser brush...
