Brush size change with zoom


Let say I started the canvas area with brush size 30,
i zoom in or out the screen, the brush size showing 30, but the circle size remain the same on screen,
means if I zoom out, the brush size is bigger than usual.

Means if i want to continue draw on the same size line, i need to remain the zoom at the initial level.

Or is this the feature of wick? lol
