Feedback from #feedback-app:

"Beachball that looks code review related. It's on a WarpDev from the 14th though, so may not still be an issue"

Attachment included a process sample (warpdev-2026-04-17.txt) showing:

  • Physical footprint around 9.2GB
  • Main-thread call graph with heavy code_review_view / local code editor activity

What needs to be done:

  • Investigate potential code-review/local editor path causing beachball and high memory usage.
  • Determine whether this reproduces on current WarpDev builds and isolate regression window if fixed.
  • Capture mitigation or fix plan if reproducible.
