IE has a lot of problems with SVG files. Make sure the SVG file has its viewport set and that your desiredSize is exactly the size of the SVG file.
I created an example below, but just realized it has a big problem. Opacity in IE works when the scale is scale: 0.1, or scale: 0.2,, but suddenly starts to fail when set to scale: 0.3,.
Unfortunately, I don’t know why IE is doing this. You may need to switch to PNGs if you want semi-transparents Pictures. Sorry for the trouble.
