Created attachment 163107 [details] video recording of the bug STEPS TO REPRODUCE 1. Open the brush editor (e.g. for Basic-5 Size) 2. Select an active parameter (e.g. Size) 3. Select an active sensor (e.g. Pressure) and modify its curve. 4. Uncheck "Share curves across all settings" 5. Observe the curves for all the other sensors of that parameter. OBSERVED RESULT Step 4 makes the curve for the selected sensor revert to its initial state, which is different from the behavior of "share curve across all settings" in 5.1.5. In step 5 we can see that the curves for some other sensors have unexpected shapes that we never defined. The set of affected sensors across different tries seems to be non-deterministic. Re-activating "Share..." on an affected sensor creates a new unexpected curve for that sensor and, contrary to the purported function of that checkbox, doesn't affect some other curves. EXPECTED RESULT Toggling "Share..." on sensor X should not change the curve for sensor X. Activating "Share..." on sensor X should set all the other sensors' curves to that of sensor X. Deactivating "Share..." on sensor X should not affect any of the curves. The behavior in 5.1.5 is keeping the curves for all the active sensors intact, while replacing the curves for the inactive sensors by the default "f(x)=x".
