This problem is quite obvious when you use a flat brush shape (or any brush with low Shape value). To reproduce:
1) Set the Angle Expression to be Direction
2) Draw vertically with a slow or medium speed
The resulted brushstroke would look like this:
It can be seen that the brush Angle keeps changing between 0 degree and 90 degree for some reason. The Direction expression shouldn't work like this.

I did another test to see how paint direction would trigger this problem:
It is clear that this problem only appears when drawing vertically.

This test is to see how paint speed (with a digital tablet) would trigger this problem:
It can be seen that the slower the brush moves, the more often the problem appears. However, if use a mouse or touch pad instead, the probelm appears almost 100% regardless how fast the brush moves.

Re: Brush Angle: Direction Error
This is caused by the latest change regarding a improved angle detection. I already aware of this issue and working on it.
