Hi Oren,
It sounds like the CSS clip isn't being removed in some IE. I'll dig deeper to see if I can find a solution. Since you already called .disable() that "should" have cleared it up but apparently it isn't working. I will check in an update on github and let you know when there's a fix. there might be a easy solution as well.
I just need to figure out the correct way to clear the CSS clip on the layer's node for the IE that is failing.
Thanks
