SUMMARY

When using a Wacom Art Pen (Intuos 4 XL) and having activated the rotation parameter for a brush, the brush cursor doesn't faithfully follow the hand movement and making brush strokes in the desired rotation angle takes more effort than it should.

STEPS TO REPRODUCE
1. Choose a brush and activate rotation (Edit Brush Settings>Rotation)
2. Rotate the Art Pen on the canvas
3. Observe the rotation of the brush cursor as the hand/stylus rotates

OBSERVED RESULT

The cursor sometimes takes a quarter of a circle to start rotating, then will "stick" for a bit when the rotation is over, before starting to rotate again.

EXPECTED RESULT

The brush should follow the hand without delaying/sticking to certain points.

SOFTWARE/OS VERSIONS
Windows: 10 
Wacom Driver: 6.3.44-1

ADDITIONAL INFORMATION

This happens with or without the Windows Ink option enabled (this sometimes causes trouble, so I usually disable it). I've uploaded a video here: https://youtu.be/eHTnLH8TFD8 Let me know if anything's unclear or if you'd like me to do specific things.

I tried this in 5.0.2 and it works like a charm. Thanks!
