The problem of frame loss after rotating the screen

Our project used IMX8MM development of Android9.0, and encountered a problem, when the screen was rotated, the frame dropped seriously.
Our analysis is as follows:
1. systrace->mytrace_normal.html before rotating the screen:
2. systrace->mytrace_dropframe.html after rotating the screen:
The main time-consuming is eglSwapBuffersWithDamageKHR function
Please help to check if there is a patch to fix this problem
