Open Blobs, zoom in, try to draw with paintbrush. Or just size the window smaller then move the scroll bars to pan. Or zoom in, then back out again. The drawn line no longer tracks the mouse properly.

As of imagej/ImageJ@1bb013f, the drawing tools are no longer wildly off, but rather always off by one data index (plus one screen pixel) in both X and Y. The bug is due to a coordinate system skew between the JHotDrawImageCanvas and DefaultImageCanvas.
