    Description

      With backend as software(QT_QUICK_BACKEND=software)

      If Rectangles with 1-pixel border or 1-pixel width/height is drawn on top of the rectangle background. Any updates triggered on the Background rectangle causing 1 px border or 1 px rectangle to vanish.

      Note: Issue occurs when the Rectangle coordinates are in float value.

       

      Reproducing steps on Sample APP:
      1.On Application launch, Click the Press button.
      Observe that the m_line Rect is missing and the borders of m_sqaure are not properly drawn.

      2.Clicking on the m_mainRect brings back the borders and lines.
