That indeed does sound very odd indeed. I wonder if a stray 
textFont/textStyle setting somewhere in the hierarchy could have crept 
in?

Hopefully that will resolve things for your current version (which I 
presume you'd rather keep at 8.x for now).

We'll take a look at the text issue in 9 - although could you check 
whether it is a similar problem? i.e. Something to do with that stack. 
That being said the problem definitely appears between two dp's of 9... 
However, it might be that something 'odd' is triggering the issue. 
(Basically we think it is something to do with the skia update we did - 
that is certainly why things are anti-aliased rather than not!).

I'm not sure what percentage of people we have using ideographic scripts 
in LC is, but it certainly isn't zero - and we haven't had any other 
reports of a problem with 9's rendering of text.

So I'm hoping it is an obscure edge-case which is being triggered by 
something specific - of course, that does make it much harder to track 
down!

Warmest Regards,

Mark.
