A bug occurs when I have the paint brush tool selected, and I'm panning with the spacebar using the left click on a normal mouse. In addition to panning normally, about half the clicks actuates the paint brush tool and paints a single click's worth of paint on the canvas. This forum doesn't let me upload videos, so here's the video showing what happens.
This is on Windows 10 64-bit with Intel i7-4790k CPU with Intel HD 4600 graphics (the integrated graphics that comes with the CPU).
Hope this helps. I'm very excited about Affinity Photo coming to Windows.
