Solve SlowRendering issue with OpenGL

We have been seeing reports of slow rendering of frames in google play vitals. When trying to debug better, it was recommended to use adb shell dumpsys gfxinfo to get more information.

Our game uses OpenGL and only 1 frame is listed when using the above command to solve the issue.

1. Any suggestions on how we can debug OpenGL applications for slow rendering.
2. Also want to understand how would google's method of slow rendering be when the game has only 1 frame.

Attaching output of adb shell dumpsys gfxinfo
