Artifacts in IE 11

I've gotten heatmap working great in chrome, but IE has some weird artifacts showing up when I zoom or pan. I appears that the edge of the image is repeated just beyond the edge of the extent.

Any ideas what's causing this?

I've managed to work around this issue by calling resizeHeatmap any time the extent changes. It's still odd that the issue only appears in IE.

  map.on('load', function () {
    if(/MSIE \d|Trident.*rv:/.test(navigator.userAgent)) {
      ieFix = map.on("extent-change", function() {
        heatLayer.resizeHeatmap(window.innerWidth, window.innerHeight); 
      });
    }
  });
