Chinese palette icons flickering - IE11

When i am loading the demo( in IE11, i could see the chinese palette icons for fraction of seconds. The same works fine in chrome.

Can someone help me to resolve this?
Because the same behavior is observed in my application too.

This is due to the fact that the font we’re using is not pre-loaded.

You may pre-load it (cf. this StackOverflow post) to prevent the flicker.
