UI InputField text sometimes invisible?

Sometimes when I change the text in an InputField in the UI, the text goes completely invisible? Any idea why this might be occurring? The text is set to “Best Fit” and can shrink down to 10 point (it normally floats around 140pt so it’d have to be a LOT of W’s before it got that small).

It mostly happens if I change the text all at once, through code, rather than typing it in myself.

I have never had this problem but I would suggest using a text field if you are going to add text through a script. In general, I noticed text fields tend to have less bugs.
