The code schedules a refresh when the renderer is not presented and skips it when the renderer is presented. Tests cover both policy outcomes and refresh behavior after the renderer loses presentation. ChangesVisibility-Reveal Refresh

- Around line 120-124: Update
testWarmVisibilityRestoreSkipsRefreshWhileTerminalIsInactive to expect one
deferred refresh when revealing a previously painted pane whose renderer is no
longer presented; rename the test to reflect that behavior. Keep the
presented-frame setup and existing refresh-count assertion helper.

- Around line 122-123: The hiddenRendererRevealSchedulesFallbackRefresh test
currently verifies only shouldScheduleVisibilityRevealRefresh; add a focused
assertion that the deferred refresh path invokes refreshSurfaceNow when the
renderer is not presented. Retain the assertion that a presented renderer does
not schedule a refresh, and use the existing production call path rather than
changing it.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Assertion on a deadline-bounded poll is deterministic. The poll can still return early for
expected == 0.The poll predicate is
debugForceRefreshCount() >= expected. If a caller passesexpected: 0, the predicate is true at once. The wait then does nothing, and the followingXCTAssertEqualcannot detect a late refresh. The current callers pass only1, so no test is affected now. A future caller withexpected: 0would get a false pass.Consider a precondition on
expectedto prevent this misuse.Proposed guard
+ precondition(expected > 0, "Use a dedicated no-refresh test for expected == 0") surface.setRendererPresentedFrameForTesting(presentedFrameBeforeReveal)

Summary
Terminal panes that had painted before a workspace switch can remain black when they are revealed. The reveal fallback now checks whether the renderer is currently presented instead of whether it has ever presented a frame, so an occluded or lost drawable schedules one coalesced redraw after the pane is visible.

Changelog
Fixed: Terminal panes repaint after a workspace reveal when their renderer is no longer currently presented
Checklist
Note
Medium Risk
Touches macOS terminal visibility and deferred main-queue redraw policy; wrong gating could cause black panes or extra blocking Metal work, but the change is narrow and heavily regression-tested.
Overview
Fixes black terminal panes after switching workspaces when a pane had painted before but its Metal renderer is no longer presenting when it becomes visible again.
The deferred visibility reveal refresh gate in
GhosttySurfaceScrollViewnow keys offisRendererPresented(current renderer health) instead ofhasPresentedFrame(historical warm-frame state), so a stale “already painted” flag no longer skips the coalesced recovery redraw. When the renderer is already presenting, the deferred callback still bails out to avoid a redundant blocking refresh.Tests were updated and expanded: policy tests rename the warm-reveal scenario, integration tests expect a redraw after renderer loss while inactive, and a new case asserts that a live presenter skips
debugForceRefreshCountwhen the deferred guard runs.Reviewed by Cursor Bugbot for commit 65f0071. Bugbot is set up for automated code reviews on this repo. Configure here.
