Description Dmitry 2016-09-01 09:48:23 UTC

My graphic tablet is PARBLO A610. 
I use pen to launch program and create new file.
And I can use the pen to drawing but it's pressure doesn't works. I tried several brushes and result was the same.

Reproducible: Always

Steps to Reproduce:
1. Launch the program and create new file.
2. Select the brush that has pressure option (e.g. basic_tip_dafault).
2. Start drawing with a tablet pen performing a different pressure.

Actual Results:  
Solid lines, regardless of the pressure.

Expected Results:  
The width and/or transparency of the drawn line changes depending on the pen pressure.

Krita 2.9.11 has the same bug. But I can avoid it when launch the program and create/open file by using tablet pen.

Hi Dmitry,

Unfortunately we don't have access to this tablet brand so it's unlikely we will be able to support it. The smaller brands of tablets usually have a very bad quality driver on Windows, where the problem is that the driver was not written to conform to the specification but to what Photoshop expects.

Hi,

You might be able to get your tablet to work by enabling the Windows Pointer API in the tablet settings of Krita, but we cannot support tablets of this brand. It's also quite likely that it's just a broken wintab driver.
