I just updated to macOS Catalina and system labels (like the ones created with
cocos2d::Label::createWithSystemFont) are not showing properly.
Following the code in Device-mac.mm, it looks like the bitmapData obtained from the NSBitmapImageRep has 16 bit depth rather than the 8 bit expected.
This is also happening with apps compiled on High Sierra (i.e., without recompiling them).
Can someone confirm this?
