SUMMARY STEPS TO REPRODUCE 1. Select calligraphy tool 2. Enable "Use tablet angle" 3. Draw using a tablet & pen that supports tilt, and vary the pen's angle by tilting and rotating the pen as you draw. OBSERVED RESULT Pen angle in the resulting stroke stays constant. EXPECTED RESULT Pen angle in the resulting stroke should vary as the pen is rotated. SOFTWARE/OS VERSIONS Platform independent. ADDITIONAL INFORMATION The source of the bug has already been identified. Lines 200-202 of KarbonCalligraphyTool.cpp cause tilt to be ignored on devices that support tilt. Creating this issue to reference in a PR with a fix.
