Hi @Hung,
Thanks for your post and being a part of the Cesium community.
Are you able to provide a sandcastle example https://sandcastle.cesium.com/ that reproduces the problem you are seeing? This will make it easier for us to evaluate and address the issue you are seeing and hopefully quickly drill down on the root cause.
Please let us know if we can help with getting the sandcastle example together.
I discovered that the issue was related to my specific computer configuration. When I ran the project on a different machine, the bug no longer appeared.
