Hi Cuboctahedron,

Is it that you're getting the bold one when you start on the left and drag towards the
right and the anemic one when starting on the right and dragging towards the left?

The left to right one displays with solid lines and will capture only things completely
contained inside the window.

The right to left one ("crossing window") displays with dashed lines and will target
anything that touches the rectangle, not just completely contained within.

The dashed line one is doing a color / transparent / color / transparent type dash
pattern. I'll see about switching it to a dark / white / dark / white pattern instead
like construction lines have now in the dark theme.

Thanks for showing the problem.
