Whiteout sensor stabilizing/line ending smoothing my line endings will look jagged - instead of constant change in size, it goes in large steps. This may be related to the fact that Krita seems to add my tablet three times. This happens in 2.8 as well since months at minimum. Reproducible: Always Steps to Reproduce: 1. Turn off smoothing/stabilizer for line endings/sensor 2. Enable pressure -> size dynamics 3. Draw a quick line, lifting up the stylus sharply at the end Actual Results: Jagged line with size changing in big steps Expected Results: Size changing relatively smoothly Tablet: Genius MousePen i608x (The newer version with 2048 pressure levels) Console output running Krita: [storm@Camelot] (~) $ krita isRunning -1 ################################### # Adding a tablet device: Genius MousePen i608X Device Type: "Stylus" # Building tablet axes remapping table: Abs X 0 -> 0 Abs Y 1 -> 1 # Axes limits data X: 0 20480 Y: 0 15360 Z: 0 0 Pressure: 0 16 Rotation: 34295672 0 T.

Hi, Storm! Here i get quite ok lines: http://pbrd.co/1xLR7vD Could you please do two things: 1) Make a screenshot of the options you use (and a paintop preset name) 2) Generate a tablet event log for a single line like that https://answers.launchpad.net/krita-ru/+faq/2495 Then I could probably understand what is happening there.
Git commit eec114f5071d455d076e04ed0e39a536af8e8f5c by Dmitry Kazakov. Committed on 19/01/2015 at 10:06. Pushed by dkazakov into branch 'calligra/2.9'. Add a workaround for broken Genius Tablet with partial pressure updates If you have lines like in bug 342641, please add the following line into your kritarc: workaroundX11SmoothPressureSteps=3 After that restart Krita and you'll see a message like: "WARNING: Workaround for broken tablet pressure reports is activated. Number of smeeth steps: 3" The problem should go after that.

This helps, but still didn't get rid of it completely, even after upping steps from 3 to 5. Actually I think this issue results from the fact that this tablet doesn't work properly under Linux/KDE in general, so perhaps it needs to be fixed on a system level first, and that may in fact fix the issues with Krita as well.
Okay, then I think we can close this bug now.
