cmux NEXT: session hover cards and the What's New popover are glass again, not solid by teamleaderleo · Pull Request #23740 · manaflow-ai/cmux

teamleaderleo · 2026-10-21T21:13:20Z

Leo on his nightly, 2026-10-21: "WHY IS THIS SOLID COLOR AGAIN". The What's New popover beside the Update Ready card and the sidebar's session hover cards showed as solid cards. They should be glass in the shared material.

Cause

All of these show in one window, the app's hover card window (HoverCardPanel): the workspace/session cards, the tab cards and the Update Ready card's highlights popover ("1 Switch fonts in a step…", "See all changes →"), which presentOwned puts in that same card.

cmux-next: overlays are themed Liquid Glass, and tooltips let more through #21785 (Leo, 2026-10-19) made every text overlay themed Liquid Glass, after Leo said of the session hover card on 2026-10-19: "it's solid gray?"
ccde782 ("floating cards are mostly opaque with a clear rim (one CardMaterial)", lawrencecchen, 2026-10-20, a direct push to feat-cmux-next with no PR) put the CardMaterial fill under the content of every theme-tone Glass.makeOverlayPanel, at 90% or more opacity: the solid popup surface. The hover card window was included, so the session cards and the What's New popover became solid again. That is the regression.
The Update Ready card (CardSurfaceView) was already the shared neutral glass veil (FloatingGlassStyle.card, 22% dark / 45% light) since 17228e1, and it still is. This PR doesn't change it; the new test guards it.

Change

Glass.makeOverlayPanel takes cardFill (default true). The palette, popovers and find and prompt bars keep the card fill Lawrence asked for.
HoverCardPanel and the hover card gallery host pass cardFill: false. They draw the shared themed overlay glass alone: Liquid Glass tinted with Palette.glassTint × glass.overlayTintStrength, or the behind-window blur before macOS 26.
Reduce Transparency stays the solid popup surface.
Only the material changes. The card's position and anchoring are untouched, so this doesn't collide with the sibling hover card alignment fix.

Invariant

FloatingSurfacesStayGlassTests (CmuxNextDesignTests, run by the swift test job when CmuxNextDesign changes) fails when:

the hover card window's surface is a CardMaterial card again, or any fill between its material and its content is denser than the shared glass (the FloatingGlassStyle veils and the themed overlay tint). It checks both Liquid Glass and the pre-26 blur, in a light and a dark theme;
the hover card gallery host stops matching;
the Update Ready card's CardSurfaceView stops being the shared veil.

A control case proves the check catches the 90% card fill. The source-level no-opaque-glass ast-grep rule (#23366) didn't catch this regression because the fill sat on a separate view laid over the glass. This test checks the fill values the views actually draw.

Changelog

Fixed: Session hover cards and the Update Ready card's What's New popover are glass again instead of a solid card.

Observed / Not run

On the fleet (cmux-ci step 94e713e351661d3c61bcf815, aws-m4pro-4, Xcode 26.6) at head 763689a, package-test-lane.sh suite Packages/macOS/CmuxNext built CmuxNext with its tests, so the Swift compiles. These suites ran and passed: FloatingSurfacesStayGlassTests (new), HoverCardGlassTests, CardMaterialLegibilityTests, FloatingGlassStyleTests, WorkspaceHoverCardSurfaceTests and UpdateCardHoverParityTests.
Not run: the new test's red at the base. At the base, HoverCardPanel().glass.isCard is true and its tint view fills at the CardMaterial opacity (≥ 0.9), which is what theCardFillTheHoverCardDropsIsSolid asserts is caught.
No capture: the fleet capture client isn't installed on this host (cmux-ci capture needs an HQ checkout, and cmux claude-team 模式开启多subagent后，如何指定模型分配 #2713 isn't deployed). The change is the hover card's fill alpha, and the tests above check it on both materials. A light/dark capture will follow.

…t a solid card Leo 2026-10-21 on his nightly: "WHY IS THIS SOLID COLOR AGAIN". The app's one hover card window (session and tab hover cards, and the Update Ready card's What's New highlights popover) was themed Liquid Glass after #21785; ccde782 then laid the mostly opaque CardMaterial fill (at least 90%) over every theme-tone overlay, this window included, so these cards read as solid again. Glass.makeOverlayPanel takes cardFill (default true, so the palette, popovers and bars keep the card fill); HoverCardPanel and the hover card gallery host pass false and draw the shared themed overlay glass alone. Reduce Transparency stays solid. FloatingSurfacesStayGlassTests fails when a fill between the hover card's or the Update Ready card's material and its content is denser than the shared glass (FloatingGlassStyle veils, the themed overlay tint), on Liquid Glass and on the pre-26 blur, and proves the check catches the card fill.

Review (subagent, correctness first): SHIP at 763689a

Change is correct and scoped. cardFill: false only reaches HoverCardPanel and HoverCardGalleryHost. Every other theme-tone makeOverlayPanel caller keeps CardMaterial through the default. Neutral-tone panels are unchanged.
What's New popover is covered. It goes through presentOwned, which uses the same HoverCardPanel. Its webview document is background: transparent (surface.css), so dropping the native fill makes it glass and leaves no second background. The workspace card body paints no fill (WorkspaceHoverCardSurfaceTests).
Reduce Transparency is unchanged. The .opaque path still paints Palette.popupSurface with a separator hairline when isCard is false.
No accent change. The tint is the theme's glass tint.
New test. FloatingSurfacesStayGlassTests reads fills the way CardMaterialLegibilityTests does, skipping GlassPanelView internals. The control case is real: card fill >= 0.9 against a ceiling of about 0.63. Its only diagnostic is a redundant-#require warning at line 24. No new lint was added; the PR body explains why a runtime test replaces one.

Risk, not a blocker: hover cards no longer carry the 4.5:1 guarantee CardMaterial gave them. The bare tint is about 50% (dark) or 37% (light) of the theme background over the glass. This reverses ccde782 (lawrencecchen, "too liquid glassy") for these surfaces, per Leo's 2026-10-21 call. Dark themes over bright backdrops are the case to check in the capture.

CI on 763689a:

Compiles: Release compile (Xcode 26) and fleet test-compile both passed. In swift test, swift build --build-tests finished ("Build complete!").
swift test is red. Seven failures, all in files this PR doesn't touch: PageWebViewDebugHover, PalettePickerSources, AttentionSteady, WindowScreenshot, AgentCursorNameTag, ActionRunCreated. The test helper also ended with no summary line, leaving 1242 tests unfinished. That includes this PR's theHoverCardWindowIsGlassNotASolidCard, plus the existing CardMaterialLegibilityTests and HoverCardGlassTests.
The new suite therefore never reported a pass. Re-run swift test before merging and confirm FloatingSurfacesStayGlassTests passes.
PR capture check is red: no capture in the description yet.

…dow (stacked on #23801) (#24022) * cmux NEXT: hover cards and the What's New popover are glass again, not a solid card Leo 2026-10-21 on his nightly: "WHY IS THIS SOLID COLOR AGAIN". The app's one hover card window (session and tab hover cards, and the Update Ready card's What's New highlights popover) was themed Liquid Glass after #21785; ccde782 then laid the mostly opaque CardMaterial fill (at least 90%) over every theme-tone overlay, this window included, so these cards read as solid again. Glass.makeOverlayPanel takes cardFill (default true, so the palette, popovers and bars keep the card fill); HoverCardPanel and the hover card gallery host pass false and draw the shared themed overlay glass alone. Reduce Transparency stays solid. FloatingSurfacesStayGlassTests fails when a fill between the hover card's or the Update Ready card's material and its content is denser than the shared glass (FloatingGlassStyle veils, the themed overlay tint), on Liquid Glass and on the pre-26 blur, and proves the check catches the card fill.

WE HAVE GLASS, SO JUST USE GLASS." - Glass.makeOverlayPanel's card fill is opt-in (cardFill defaults to false): the palette, popovers, menus, find and prompt bars, browser bubbles and page info draw the shared themed glass alone. Takes back ccde782 (no PR), which laid the mostly opaque CardMaterial fill (90% or more) on every overlay. Reduce Transparency stays solid. - The notifications panel and New Message's recipient suggestions sit on the shared overlay glass instead of the elevated / popup surface. - Home's import cards are real glass with the dialogs' neutral veil and rim, not ReduceTransparency.alwaysOpaque. - The sidebar's edit bar draws the sidebar cards' veil, solid only under Reduce Transparency. - check-overlay-glass.py (cmux-next checks job, the prepush gate, and its own test) names every solid surface fill in CmuxNext: the popup surface, elevated fills, solid system colors, alwaysOpaque, cardFill: true and solid SwiftUI backgrounds. A hit passes only with a listed reason or a `glass-opaque-allow:` comment, and a stale allowance fails. - FloatingSurfacesStayGlassTests: every default overlay is glass.

Each body is glass today, but nothing stopped one from building its own window or material or laying a solid fill over the panel's glass. The lint now finds hover card bodies (files with HoverCardBody(...) or HoverCardTextReporting) and flags: hover-own-window NSPanel / NSPopover / NSWindow / NSVisualEffectView / OverlaySurfaceView / makeOverlayPanel in a body; hover-body-fill a backgroundColor / fillColor / .background(...) that isn't Palette.hoverFill, clear, nil or a color under 0.6 alpha (each ternary branch is checked). The existing glass-opaque-allow escape and ALLOWED table apply. The shell test adds fixtures for each form and the passes.
