When you have an assistant active that lets you start a line anywhere on the canvas (like the parallel ruler or vanishing point), you will get guidelines attached to your brush that show you how the lines would look if you drew. When you actually draw a line and the brush locks onto the assistant, and when you stray away from the ideal line with your pen, the guide lines will follow the (otherwise invisible) pen position instead of the locked brush position. STEPS TO REPRODUCE 1. Create a parallel ruler assistant 2. Select the brush tool and enable "Snap to assistant" in the tool options 3. Start drawing a line 4. Move your pen away from the ideal line while you keep drawing the line OBSERVED RESULT The guidelines that show you where the assistant will snap to will follow your pen position, while your brush position is locked to its current line. EXPECTED RESULT Guidelines will stick with the brush. It's only a minor thing, but with a tiny brush, it can get confusing where you are actually drawing.
