On android, android's nsWindow creates LayerManaer only in nsWindow::Create(). When WebRender error happened, gecko just stopped rendering by disabling Webrender. The nsWindow needs to re-create LayerManager during disabling Webrender. Further, during disabling WebRender, All GeckoSurfaceTextures should not be attached to GLContext. It is for preventing a conflict with AttachToGLContext() call in SurfaceTextureHost::EnsureAttached().
