XDRIVER itself doesn't display floating-point data; it must first be
converted to either char or int by displaylib.

I need more details (i.e. a specific test case using publicly
available data, plus details of the Visual being used) before I can
look into this. Simple tests don't show anything odd.

That's inevitable; it's just the way that malloc/free work.
