Instruments 15.0.1: Unintended Recording of Additional Process Traces

I'm tracing a process, specifically focusing on the Metal device track, which records frames from other processes like Terminal, WindowServer, and sometimes processes that utilize the GPU.

I attempted tracing with all apps closed and only Instruments running. However, it also records traces for Instruments.

This behavior wasn't present in previous versions of Instruments. Was there a recent change in Instruments/Xcode 15.0.1? I cannot find any relevant information about this in the release notes either.

Is there a way to configure Instruments to record only the running process?

This just adds a lot of noise to the profiling data and would be nice to configure it.
