I'm trying to integrate native OpenGL rendering by exposing GLSurfaceView as PlatformView.
On my Nexus 6P (Android 8.1) the performance is quite bad, rendering is not smooth.

Here is a complete example:

    #53533 can be a solution in some cases.

    Thanks.
    It's better to measure performance in profile mode rather than debug.
    Also the Flutter performance overlay is not the only criterion. It is possible that the Flutter UI is rendered smoothly, but the PlatformView content is not. Therefore, there is an additional performance indicator - a rectangle in the lower left corner. When performance is good, it should be solid purple.
