    Description

      Example component:

          Repeater {
              id: rep
              model: 330585
              delegate: Rectangle {
                  x: index%500;
                  y: Math.floor(index/500);
                  width: 100
                  height: 100
                  radius: 25
                  color: Qt.rgba(index%255/255, 0, 0, 1)
              }
          }
      

      is rendered ~3s on my machine.

      When I increase model by only 1:

          Repeater {
              id: rep
              model: 330586
              delegate: Rectangle {
                  x: index%500;
                  y: Math.floor(index/500);
                  width: 100
                  height: 100
                  radius: 25
                  color: Qt.rgba(index%255/255, 0, 0, 1)
              }
          }
      

      it renders more or less forever. Do you have any idea why? I didn't notice 330586 to be any special number (like 2^n).
