zygote exit due to skia failed to open fonts

[muare]

since the libskia.so is the one from MIUI PATCHROM project, so any idea for this issue?

in normal way, the skia should open the fonts under /system/fonts

so I workaround this issue by copy /system/fonts to /data/fonts. what is the root cause for the MIUI customized libskia.so to find fonts under /data directory? would you please help for explaination?
