in portrait mode, the performance is very slow. The maximum frame rate is only about 10 fps

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
