SUMMARY For blending, I use a flat soft brush, the shape of which is perpendicular to the direction of drawing. The brush tip acts extremely jumpy, even if the stylus is held perfectly still, the brush tip rotates erratically. STEPS TO REPRODUCE 1. Create a flat brush, perpendicular to direction of movement 2. Hold it still on the Wacom tablet. OBSERVED RESULT The orientation of the brush tip changes erratically. EXPECTED RESULT The orientation of the brush tip ,atches the movement of the stylus SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Ubuntu 18.04.2 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Using a Wacom Cintiq DTZ-1200W
Could you please attach the preset is giving you troubles? I tried making a brush as you explained but I don't get any erratic change.

Hi, Thanks for your report. I can reproduce the issue with your preset. When looking at the tablet log, I see that my tablet reports a continuous change in position, even when holding the pen in the same place, so we might have to apply some filtering or delta here. krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 147, 696 gpos: 1510, 822 hires: 1509.76, 821.737 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -6 yTilt: 8 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 147, 696 gpos: 1510, 822 hires: 1509.76, 821.737 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 146, 695 gpos: 1509, 821 hires: 1509.19, 820.934 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -6 yTilt: 9 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 146, 695 gpos: 1509, 821 hires: 1509.19, 820.934 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 146, 694 gpos: 1509, 820 hires: 1508.56, 819.705 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -6 yTilt: 9 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 146, 694 gpos: 1509, 820 hires: 1508.56, 819.705 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 145, 692 gpos: 1508, 818 hires: 1508.06, 817.768 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -5 yTilt: 8 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 145, 692 gpos: 1508, 818 hires: 1508.06, 817.768 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 144, 689 gpos: 1507, 815 hires: 1507.05, 815.028 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -5 yTilt: 5 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 144, 689 gpos: 1507, 815 hires: 1507.05, 815.028 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 143, 686 gpos: 1506, 812 hires: 1505.54, 811.58 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -5 yTilt: 0 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 143, 686 gpos: 1506, 812 hires: 1505.54, 811.58 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 140, 682 gpos: 1503, 808 hires: 1503.14, 807.753 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -4 yTilt: -5 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 140, 682 gpos: 1503, 808 hires: 1503.14, 807.753 Source:2" krita.tabletlog: "[ ] TabletMove btn: 0 btns: 0 pos: 136, 678 gpos: 1499, 804 hires: 1499.18, 803.737 prs: 0.000000 Stylus Pen id: 760335049171 xTilt: -2 yTilt: -11 rot: 0 z: 0 tp: 0 " krita.tabletlog: "[BLOCKED 2:] MouseMove btn: 0 btns: 0 pos: 136, 678 gpos: 1499, 804 hires: 1499.18, 803
