    canvas.putImageData doesn't draw bitmaps properly with HD Graphics v9.18 drivers


      Steps to reproduce:


      1. Run IE11 on a system with Intel HD graphics 4600 version drivers. We've seen this with IE 11.0.9600.17420.

      2. Open http://jsfiddle.net/philci/j3a284L3/

      3. Click on the square on the right-hand side

      4. A bitmap with shades of blue should appear, but instead the square turns white

      5. Comment out the clearRect call in the code, click Run and click on the square again. This time it works OK.


      The problem does not occur on other browsers (Chrome, Firefox) on the same platform; nor does it occur in IE11 with Intel version 9.17 drivers.
