macOS 15.2, MBP M1, built-in display.
The following code produces a line outside the bounds of my clipping region when drawing to CGLayers, to produce a clockwise arc:
CGContextBeginPath(m_s.outContext);
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -startRads, -endRads, 1);
CGContextSetRGBStrokeColor(m_s.outContext, col.fRed(), col.fGreen(), col.fBlue(), col.fAlpha());
CGContextSetLineWidth(m_s.outContext, width);
CGContextStrokePath(m_s.outContext);
Drawing other shapes such as rects or ellipses doesn't cause a problem.
I can work around the issue by bringing the path back to the start of the arc:
CGContextBeginPath(m_s.outContext);
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -startRads, -endRads, 1);
// add a second arc back to the start
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -endRads, -startRads, 0);
CGContextSetRGBStrokeColor(m_s.outContext, col.fRed(), col.fGreen(), col.fBlue(), col.fAlpha());
CGContextSetLineWidth(m_s.outContext, width);
CGContextStrokePath(m_s.outContext);
But this does appear to be a bug.
