Use Chrome tracing [1] or Perfetto [2] to take a couple of trace when the problem is happening. Then submit a bug with the trace. That's one of the most promising way to report performance bugs. It is especially powerful when you're using Chromebook because Chrome OS integrates Linux ftrace to these app-level tracing and draws a system-wide picture of the workload.
