Arm Mali Gpu(Mali-T880) issue

Hi,
  I compile own chrome_public_apk based on M74 on Android, and when running on Arm Mali gpu(Mali-T880) device,  it has two issues:
  1. gl::NativeViewGLSurfaceEGL::SwapBuffers crash frequently, the back trace as follow:
    #00 pc 0004911c pthread_mutex_lock LINE:libc.so
    #01 pc 002bebbc osup_sync_object_wait LINE:libGLES_mali.so

  2. gpu::GpuWatchdogThread::DeliberatelyTerminateToRecoverFromHang() , gpu thread in gpu process blocked at glFinish, stack trace as follow:
    00 pc 00017408 syscall LINE:libc.so

    07 pc 00bf4379 gpu::CommandBufferService::Flush(int, gpu::AsyncAPIInterface*)
    08 pc 00c8a623 gpu::CommandBufferStub::OnAsyncFlush(int, unsigned int)

Is there any suggestion? Thanks
