FontFreeType performance issues on Android #2063

Closed smilediver closed 3 months ago

We have big performance issues on Android when creating Labels. It looks like the issue is that FontFreeType is not loading whole font file into memory, but is reading it like a regular file from APK. Reading from APK seems to be super slow (maybe only random seeking?). Profiler shows that it takes 8ms for reading glyph data. I have suspicion that it might be decompressing whole font file each time it is accessed.

Check your build.gradle does the noCompress contains ttf, ttc
