The problem is that the official FAA sizes (0.76 meters, for example) suffer from tiny rounding errors when put through the sign creation process. (Use 0.33 as a proxy for 1/3rd. Divide something in thirds and add it up. You lose a tiny sliver, right?) That warning message was the renderer noticing that it was being asked to fill in a really tiny sub-pixel area (which it then did, hence you can't see a problem from your airplane).
With 920, the sign heights are changed ever so subtly (by less than 0.1%!) so that they don't cause rounding errors. This is the equivalent of calling the sign 0.33 meters instead of 1/3rd meter.
If this all seems like decimal point hell, well, welcome to my world!
Bottom line: you can ignore this warning, it'll go away in 920.
