Short description of error
I have 2 graphics tablets - a Huion 610Pro and an XP-PEN Artist 12 - and both exhibit the same behavior: unable to draw in 2d mode.
Exact steps for others to reproduce the error
- Open Blender
- Choose 2D Animation from the splash screen
- Can draw using the mouse
- Bring tablet pen onscreen (don't need to click, simply moving the cursor with the pen does it)
- Can no longer draw with mouse(!)
- Cannot draw with pen
Both tablets work perfectly fine in other applications (eg Photoshop). I actually bought the XPPen because I thought the Huion was old and maybe that was the issue.
The bizarre thing is that simply moving the cursor with the tablet causes the issue. You do NOT need to touch pen to tablet and try to draw.
I tried this with 'clean' settings (i.e Load Default) and also with Emulate 3 Button Mouse.
I also turned on Screencast keys to see if some command was being issued by the tablets, but I see nothing coming through.
