What steps will reproduce the problem?
1. Install Mozc 2.16.2007.103 to Nexus 5 / Android 5.0.1 (LRX22C)
2. Install AOSP keyboard (based on android-5.0.2_r1)
   https://android.googlesource.com/platform/packages/inputmethods/LatinIME/+/android-5.0.2_r1
3. Make sure that only Mozc and AOSP keyboard are enabled.
4. Tap any text field to show the keyboard.
5. Dump memory resources of Mozc with adb as follows.
   adb shell dumpsys meminfo org.mozc.android.inputmethod.japanese
6. Tap the Globe key again and again to rotate keyboards between Mozc and AOSP 
keyboard.
7. Dump memory resources of Mozc with adb again.

What is the expected output?
Memory resources is not steadily increasing.

What do you see instead?
Views count and GL memory increase in proportion to the iteration count.

Please use labels and text to provide additional information.

Here are some outputs of 'adb shell dumpsys meminfo' command.
