Hi, I've been using Autodesk Sketchbook on my Android for about 2 years. I've downloaded the most recent update, and this still doesn't solve a problem that I've been recently experiencing... namely, whenever I use the tools that I've used many times in the past [pencil, design pencil, paintbrush, etc.] I keep getting extremely rough edges. If I, for instance, use the pencil at about size 3, freehand, it does not give me a smooth flowing line as it used to. Even if I use the 'straight line' tool, it gives me a line, but the line is very jagged and not smooth at all! Can you tell me why this is happening? Thanks!
