MGD processlist.cfg does not work

i am trying to use MGD in Galaxy S6 64bit device.

if i don't use processlist.cfg, MGD is working fine.

However, if i create processlist.cfg to /system/lib/egl , MGD does not work.

i made processlist.cfg by

echo "com.test.app" > /system/lib/egl/processlist.cfg

Here is logcat .

There is some "whitelist" error and tracing fail.

with processlist.cfg  ( MGD does not work  )
