A graphical object is rendered to a pixel buffer, such that a software application executing on a computing device displays the contents of the pixel buffer via a user interface. An invisible element is created and positioned under the cursor in response to detecting that the cursor is positioned over the feature being displayed via the user interface. The software application automatically repositions the invisible element in accordance with a movement of the cursor. A change in the position of the invisible element is determined, and the graphical object is repositioned within the pixel buffer in accordance with the change in the position of the invisible element.
