Text rendering of Unicode text in LC

[Peter Bogdanoff]

Hi Mark,

I’ll file the bug report.

On the other issue I had with the “blurry” text in LC 8. Now I’m seeing that text with the faulty rendering is only in a main stack. All substacks of that stack that use the same font have normal, good rendering. This issue appeared only recently--earlier runtimes created for Windows users were all OK, but the runtime created a week ago was bad. So I’m thinking some sort of corruption in the main stack? The bad rendering shows on all cards and in different backgrounds of that stack only, and only in Windows.

I’ve rebuilt the main stack by copying cards, custom properties, and stack script over to a new stack. I’m sending that new version to our translator in China for her to test to see if that improves the situation.

Thanks again for your help!

Peter

For what its worth, I think its definitely a font issue of some kind - we'll take a look at the lighter looking ideographs in comparison to the darker ones to see if we can determine if it is related to 'font fallback'.
