--Issue Summary--

When using a tablet, wrong cursor icons are displayed, for instance, I select the drawing pen, then I
move the cursor into the drawing area. While doing so I pass a window border, which changes the cursor to a "move border arrows" icon, the icon stays when I move the cursor into the drawing area. This makes it hard to aim at the exact position where you want to start painting.

As soon as I draw a pixel the icon corrects itself.

The screenshot tool would always capture a normal cursor and not the icon displayed, so I had to photograph my screen :)

--Steps to reproduce--

Use your tablet pen to select a drawing tool, then move into the drawing area, observe the pen cursor/pointer icon.
