Selector indicates light source at zero degrees, but light source appears to be at 90 degrees.

In the Layer Styles, styles which allow for the selection of lighting direction, the selected lighting direction does not correspond to the resulting light direction in the effect.

Create a layer.  Fill it with 50% grey.  Create another layer.  Paint several hard-edged spots in a contrasting color.  Pull up layer effects and check "Drop shadow" or "Bevel and Emboss."  Uncheck "Use Global Light" and check "Preview"  Play with the lighting direction and note the following:

The location of the spot on the rotary graphic selector corresponds to neither the direction of the shadow, nor the apparent direction of the light source.  Also note that as the angle is increased in the numeric selector, the spot on the graphic selector rotates clockwise, while the shadows on the canvas rotate counter-clockwise.

EXPECTED BEHAVIOR:  The spot on the graphical rotary selector would represent the light source, and drop shadows would appear opposite from it's position.  Also, when rotating the selector clockwise, the shadow would progress around the object casting it in the clockwise direction.

(I can confirm this behaviour on Ubuntu 14.04 - Krita 4.0.0-beta1.1.appimage)

Maybe the selector right now seems not very intuitive when thinking in terms of cartesian coordinate system... a solution might be:

1) moving the dot on the right (0 degrees)
2) inverting the rotation direction. 

PS. however it does increases and decreases the lighting angle correctly yet

Yes, I think so.
