Dynamic font is used, occasionally appears strange characters.

[nicecapj]

In the context of using the Dynamic font, the UI that includes a lot of the text is loaded at the same time, the text will appear strange.
Forced to call a "OnFontTextureChanged" but, did not improve.
Not always,will appear with a low probability.
When viewing the font texture, looks normal, change the option of changing or anything uilabel to normal. I feel should not be updated.

I have attached a screen shot.

Is there enough information, or reference solution?


UNITY 4.5.5f
NGUI 3.6.8

thank you.

Note the warning that appears in inspector when you use dynamic fonts on labels...
