Summary

The HUD grants HUD_GROWTH_RESERVE (120px) beyond its required size on each axis — +240px width, +120px height — as hysteresis against native resizes. On Windows and macOS that overhang is click-through, so it is invisible and harmless. On Linux the HUD is deliberately not click-through (setHudMouseEventsEnabled is skipped when isLinuxHud), and a Wayland compositor treats the whole toplevel as the window's allocation, so any reserve is a transparent rectangle around the bar that swallows desktop clicks.

This makes the Linux window follow what is actually visible instead:

• hudGrowthReserve(platform) returns 0 on Linux, so granted equals required.
• computeHudWindowSize accepts openStackHeight (the measured stack above the bar) and toastsHeight. Linux passes the measured stack, so the window is the bar plus a tooltip floor while collapsed and the open panel's height while one is open — and it shrinks back when the panel closes. Windows and macOS keep reserving the tallest panel and are unchanged.
• Window height now counts the visible toast stack on every platform. The growth reserve used to cover it on Windows/macOS; on Linux, where the window hugs the bar, omitting it cut the toast off.
• +toastsHeight also feeds needsResize, so a toast appearing or leaving triggers exactly one resize.
• On Linux the fixed min/max size hints from resizable: false are lifted around setBounds, because Mutter otherwise ignores the programmatic resize, and the window starts at the compact bar size instead of the old 820×560 reserve.

Testing

  • New: toast height is counted in required/granted; openStackHeight replaces the panel reserve without double-counting a notice; LaunchWindow resizes on bar grow/shrink, grows for an open panel then shrinks back when it closes, and counts a visible toast in the window height then gives the room back.
• npx tsc --noEmit and npx tsc -p tsconfig.test.json --noEmit — clean.
• biome check on the changed files — clean.
• Full npm run test: all 4963 loadable tests pass. 20 Electron-importing files could not load in this environment because npm install blocked Electron's postinstall binary download (npm 12 allowScripts), unrelated to this change.

Summary by CodeRabbit

• Bug Fixes
  • Improved launch overlay sizing on Linux so its width tracks the bar more closely and its height adjusts to open panels and notifications, reclaiming space when they close.
  • Reduced excess space in the collapsed Linux overlay while preserving room for tooltips.
  • Preserved growth room on macOS and Windows so the overlay can accommodate larger panels and notifications without frequent resizing.

Walkthrough

HUD window sizing now uses platform-specific growth reserves and measured stack dimensions. Linux sizing includes tooltip and toast space. Electron applies HUD bounds through a helper that temporarily enables resizing on Linux.

Changes: HUD sizing

Layer / File(s)	Summary
Platform reserve and size calculation src/components/launch/hudGeometry.ts, src/components/launch/hudGeometry.test.ts	hudGrowthReserve returns zero for Linux and the existing reserve for other platforms. computeHudWindowSize accounts for toast height and can use a measured open-stack height instead of popover and notice reserves. Tests cover reserve selection and size calculations.
Measured stack sizing and toast placement src/components/launch/LaunchWindow.tsx, src/components/launch/LaunchWindow.test.tsx	LaunchWindow uses platform-specific sizing inputs and measured stack height for toast placement. Linux tests cover bar width, open-panel sizing, and toast height before and after dismissal.
Platform-specific HUD bounds electron/windows.ts	HUD reclamping and resizing use setHudWindowBounds. On Linux, the helper temporarily enables resizing while applying bounds. The initial size is 600×190 on Linux and 820×560 on other platforms.

Explanation

The title names the main change: on Linux the HUD drops its growth reserve so the window fits its visible content. It matches the summary, the objectives, and the reserve change in hudGeometry.ts. The fix(hud) prefix is conventional and the title is 70 characters, so it reads clearly in history.

Full details: Description check

Explanation

The description follows the repository template. It has a Summary that explains the Linux click-through problem and the sizing change, and it covers the toast, needsResize, and size-hint changes. The Related issue section says N/A, but the template asks for Fixes #, and no issue number is given. The Type of change, Release impact, and Desktop impact sections are filled in. The Screenshots section gives a reason for omitting screenshots, and the Testing section lists commands and results. The only gap is the missing related issue reference.

Test Linux resizing after the bar shrinks.

The test checks only the initial width. A 120-pixel shrink threshold could retain a larger click-blocking window without failing it. Measure both widths in the same HUD.

+		await flushResizeObservers();

Assert the uncapped Linux height as well as the width.

A height-only growth-reserve regression in the renderer could pass the width assertion and the capped-height test. Assert the exact requested height to cover that boundary.

Thanks for this fix, @lehkost16! CI and the CodeRabbit review are green. Two CodeRabbit threads are still open, and they are the only thing blocking the merge:

1. Toast height on Linux: include a visible toast in the Linux window size, so it stays readable above a tall settings panel. The second point in that thread (input area of closed panels) can be a follow-up if you prefer; just say so in the thread.
2. Comments: the comments near lines 385-400 and 549-552 still say a popover never triggers a native resize, which is no longer true on Linux.

Once they are addressed or answered and resolved, the PR merges automatically.
