If I alternate a text between displaying a pair of floating point numbers, e.g. 10.0005 and 5.0000, very briefly these are drawn incorrectly as 10.0000 and 5.0005, before the correct value is drawn. There seems to be a lag between the first and last character updated.
This is using snprintf() to update a char array from the float, then Unicode::strncpy() to update the text buffer from the char array, finally invalidating the text.
