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

#02 pc 005edca4 /system/vendor/lib/egl/libGLES_mali.so

2. gpu::GpuWatchdogThread::DeliberatelyTerminateToRecoverFromHang() , gpu thread in gpu process blocked at glFinish, stack trace as follow:

07 pc 00bf4379 gpu::CommandBufferService::Flush(int, gpu::AsyncAPIInterface*)

08 pc 00c8a623 gpu::CommandBufferStub::OnAsyncFlush(int, unsigned int)

Is there any suggestion? Thanks
