STEPS TO REPRODUCE 1. Open the application. 2. Put a video into the project bin. 3. Drag the video onto one of the tracks. 4. Apply Draw Box to the clip. 5. Set the Draw Box's thickness to a somewhat high value (for example 345) to be able to notice the issue more easily. 6. Make sure that width and height are set to 0. OBSERVED RESULT The box encapsulates the entire clip, as if its width and/or height were set to their maximum values. EXPECTED RESULT The box should appear as a line if either of the dimensions is set to 0 or as a point if they are both 0.
