@qisikai thanks for reporting this.

Looking at the code, the issue is that we make a call to GetProcessUtilization once to get the number of samples and then use this value in a second call to retrieve the samples. However, it is likely that more samples were generated between these two calls.

If you like, you could submit a PR for the fix (the code here should follow a similar flow to DeviceGetSupportedVgpus), or we will work on it on our end.
