- #99889: \[Bug\]: Desktop (Windows): interaction freezes dominated by style recalculation — 48% of renderer main-thread time, single recalcs up to 1.4 s over ~6k nodes (invalidation-tracking traces included)
- PR #144903: perf(desktop): typing cost no longer grows with loaded history; sticky-prompt clip stops restyling turns (salvage #120598, #133314)

The members share one theme: desktop UI freezes tied to style recalculation. One is a Windows bug report describing long recalcs over thousands of nodes, and two are performance changes targeting style recalculation cost, such as keyframes, containment, throttled measures, typing cost, and sticky-prompt restyling. Whether the changes address the report is not established by the titles.

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
