If these semicircles appear in a release build, you must: 2.15.3 debug semicircles

Version numbers like 2.15.3 often represent "maintenance releases." In many open-source repositories, this specific version introduced optimizations for path-finding and shape-tessellation. However, these optimizations sometimes result in "flat-edged" arcs or semicircles that render as full circles or disappear entirely due to a . Common Symptoms of the Bug Test these scenarios separately: If these semicircles appear

If the object’s transform (position, rotation, scale) contains NaN (Not a Number) or infinite values, the rendering engine may fall back to a default semicircle as a safe diagnostic shape. The “2.15.3” tag can appear in the console alongside a matrix warning. The “2

The point cloud processing node, version 2.15.3 of the laser_filters package, contains a debug routine that renders a semicircle representing the remaining active scanning angle (180° out of 360°).

If your semicircle is disappearing or closing into a full circle, it's likely a precision error where start_angle and end_angle are being treated as identical. To debug this, add a tiny "Epsilon" value to your end angle: javascript

The renderer fails to recognize the end_angle and completes a 360-degree loop.
