Created attachment 107478 [details] Curves of the Pressure and PressureIn sensors 1. Choose the brush “Fill_circle”. 2. Press F5. 3. In the Brush Setting window open ‘Size’ 4. Choose any other sensor except “Pressure” Default settings for “Fill_circle” brush: the “Pressure” curve is not linear, like for other sensors. And checkbox «Share curve across all settings» is active. But if you do not change the curve and choose other sensors, their curve stays the same, linear. But If you change the curve it works just fine.
Thanks, I'm changing this from Wish to Normal, though, since it does sound like a bug.
(I can confirm on Ubuntu 14.04 - Krita 4.0.0-beta1.1.appimage)
Git commit 47a5716210f2f30c3ae4c9ff22e590d1a25b877a by Agata Cacko. Committed on 14/08/2019 at 19:49. Pushed by tymond into branch 'master'. Fix curve change despite 'Use same curve' checked Before this commit, if you have a preset like Fill_circle that has "Use the same curve" checkbox checked and you were clicking on other sensors, the curve would be back to the default curve (the one that other sensors had) if you switch back and forth between some sensors (like Pressure -> X-Tilt-> Pressure). Also before this commit if you have the default uprising curve and you switched Rotation -> Tilt elevation, the curve would change. This commit fixes both behaviours (first by adding transferCurve(), second by switching the line in kis_curve_widget). This commit also includes two slot functions instead of one function that were used as a slot for two different signals. It helps with debugging signals and keeping stuff clear and ordered. There is one problem left: if you switch Tilt elevation -> Distance (using the 'hill' curve), the preset is set to modified even though the curve doesn't change.

Created attachment 122144 [details] Brush A I believe the fix I provided is only partial. Before when you switched to another preset, it would turned to the default curve. Now it won't switch to another curve, but still if you switch between some specific sensors, then because of the mismatch of ranges in the curve it will change the curve anyway. I still can see at least two issues: Brush A: if you go to Rotation and then switch between Fuzzy Dab, then Drawing Angle, then again Fuzzy Dab, the curve will change. Brush B: if you go to Size and switch between Pressure, Drawing Angle and then Pressure again, it will mark the brush as "modified" even though the curve doesn't change.

Fix curve changing with sensors w/ Use Same Curve Before this commit, curve would change semi-randomly in some cases if you change from some specific sensors to some other specific sensors (having a complex curve and clicking randomly should show a bug though) when "Share curve across all settings" is selected.
