It sounds like your problem might be not with the visualization itself, but with the underlying idea of a sampling profiler as opposed to tracing every single call from every single frame.
No. Sampling profilers are great. Most powerful is of course a mix of sampling and instrumentation. But nothing beats the feeling of a sampling profiler fixing big issues in under 5 minutes.
Flamegraphs are a nice tool to have in the bag I suppose. But they’re more tertiary than primary or even secondary to me.
