🟡 Medium components/ChatView.tsx:5940
Confirming requestClosePanelTerminal after another surface becomes active can leave the requested terminal open in the panel, or remove it from the wrong tab while closing the server terminal. closePanelTerminal re-reads the active surface after the asynchronous confirmation and passes that surface's ID to closeTerminal; capture the original surface ID before awaiting confirmation, or locate the surface containing terminalId.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR performs a broad right-panel and workspace-layout refactor that changes existing chat, preview, terminal, diff, and pull-request rendering behavior rather than making a small isolated UI fix. An unresolved Medium-severity finding also identifies a race that can close the wrong terminal surface or leave the requested one open. Not approved because:

Note 🤖 Claude Opus 5.5 on behalf of Oliver Superseded by #18077. Stabilizing the props of the three expensive children gets the same long-frame result on a production bundle with less blocking time, in about a seventh of the code. The "54 → 0" in this description was measured with the closed #18058 stacked on top, not this PR alone. If the header-icon fix from this PR turns out to be small without the state extraction, it will come as its own PR. |

Problem
Opening or closing the right panel re-renders all of
ChatView. On a long thread, that blocks the main thread while the panel animates. In dev, the panel snaps most of the way open instead of sliding. In a production build the first frame of motion arrives on time (32.5ms vs 31ms onmain), but the transition still produces long frames. The header controls also jump between positions while the panel moves, and the maximize button stays visible for part of the close animation.Change
ChatWorkspacecomponent belowChatView. Toggling the panel no longer re-renders the chat. Persisted maximize (#17327) still lives inrightPanelStore, and the OS-link maximize request is still consumed there.Related open PRs touch nearby files but fix different problems: #14094 (chat width when the sidebar toggles) and #14786 (keyboard focus inside a closing panel).
Scope and approval
There is no triaged issue for this. I'm sharing it with maintainers directly. It is a focused performance and visual fix for existing panel behaviour and changes no features. The workspace-card jump is fixed separately in #18064. That PR doesn't depend on this one, and the two touch no files in common.
Verification
tscpass.mainin headed Chromium, with 400ms panel animations:mainhad 54 long animation frames; this branch had 0.mainshowed 10 frames of overlapping controls and 110 frames with maximize lingering; this branch showed 0 of each.mainexactly.The clips were recorded with this PR and the now-closed #18058 applied together. Any workspace-card behavior in them comes from #18058, not this PR.
