All the other Brush Engines work fine in the preview, the Krita app crashes the second I put my pencil and try to draw with the "Tangent Normal" Brush Engine on the preview field. Reproducible: Always Steps to Reproduce: 1. Go to brush engines 2. select "Tangent Normal" 3. Try to draw on the preview field, immediate app crash. Actual Results: App crashes OS: Win 10 x64bit CPU: I7-4770 GPU: GTX960 Wacom Tablet
Created attachment 96227 [details] App crash when drawing in the preview field here
Could you clear you config and check if it happens again? Instructions here: https://userbase.kde.org/Krita/Manual/FAQ#Resetting_Krita_configuration
I also confirm this bug. I use recent *krita-3.0-RC-1-master-6f75b0f-x86_64.appimage*. Just downloaded it, launched, created new custom document, selected Tangent Normal brush from brush menu and tried to draw. 'Segmentation fault' appears every time I try to draw with this brush whether on canvas or preview area. I tried to remove all personal Krita data by rm -r ~/.local/share/{k,K}rita ~/.config/krita* and draw again, but it crashes all the same when I just click on a canvas with this brush.
Okay, I have a backtrace, but this is definitely for dmitry, considering it has to dow with the stroke framework. Thread 25 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

It seems like KisBrushBasedPaintOp::m_brush does not get initialized for some reason. Although there is an explicit initialization before that: if (!m_brush) { KisBrushOption brushOption; brushOption.readOptionSetting(settings); m_brush = brushOption.brush(); } m_brush->notifyStrokeStarted();

(In reply to Dmitry Kazakov from comment #6) Thanks you, Dmitry! It was fast. Typos like that are really hard to find sometimes. I stared for a minute at ids before I mentioned the differenece :)
