Problem

On Omarchy (Arch + Hyprland, Wayland) the recording HUD is unusable:

  • In the stable 1.3.3 AppImage, hovering the bar makes it vanish. The Linux fallback window grows from 160px to 540px on hover (setHudOverlayFallbackExpanded from e2802bf). Wayland ignores the repositioned bounds, Hyprland re-centres a floating window that resizes itself, and the bar (anchored to the window bottom) jumps ~190px away from the pointer, collapses, and oscillates. With the HUD at its default bottom-of-screen position the bar ends up off-screen entirely. The revert in d2796fb stopped the resize, but that leaves the popover menus clipped inside the 160px window.
  • Cursor telemetry is empty on Wayland: uiohook's XRecord hook only sees XWayland clients, so auto-zoom and click effects get no data. Verified with a standalone uiohook run: 0 mousemove events while the pointer moved across native Wayland windows.
  • Hyprland's blur/shadow/dim/opacity decorate the transparent HUD window as a grey box, and alwaysOnTop is ignored on Wayland.

Changes

  • Grow the Linux HUD window only while a popover is open (new hud-overlay-set-menu-open IPC), never on hover. On Wayland the bar is anchored to the window centre (paddingBottom: calc(50vh - 60px)) so the compositor's centre-anchored resize leaves it in place; X11 keeps the bottom-anchored layout. The anchor is reported through the existing get-hud-overlay-mouse-passthrough-supported handler.
  • On Wayland sessions, poll Hyprland's IPC socket (j/cursorpos) for the pointer position and read mouse buttons from /dev/input devices that advertise BTN_LEFT (needs the input group, which Omarchy grants by default). Other compositors keep the existing fallback.
  • README: Arch/Omarchy build deps, WHISPER_RUNTIME_ALLOW_MISSING=1, and Hyprland window rules (pin, noblur, noshadow, nodim, opacity 1 1, bordersize 0) for the recordly/Recordly class.

Fixes #600 and #638. Related: #772 (same root cause, Niri untested) and #34 (pointer position is Hyprland-only for now).

Testing

  • npx tsc --noEmit, npm run lint, npm test (1057 tests) pass.
  • Reproduced the 1.3.3 hover bug on Hyprland 0.56.2 by temporarily restoring the hover-resize: window went 860x160 -> 860x540 and Hyprland moved its top from y=473 to y=283 (same centre). With the branch, hovering leaves the window at 860x160 and the bar stays put.
  • With the documented rules, hyprctl clients reports the HUD as floating: true, pinned: true and hyprctl decorations lists none; the grey box is gone and the HUD follows workspace switches.

Linux has no hover-driven mouse passthrough, so the HUD lives in a compact
160px window and its popover menus were clipped. The earlier attempt to grow
the window on hover (shipped in 1.3.3) made the bar jump away from the
pointer on Wayland, because Hyprland re-centres a floating window that
resizes itself and the bar was anchored to the window bottom.

Grow the window only while a popover is open, and on Wayland anchor the bar
to the window centre so it stays put through the resize.
uiohook only sees XWayland clients, so under a Wayland session it reports no
pointer motion or clicks and auto-zoom and click effects have nothing to work
with. Poll Hyprland's socket for the pointer position and read mouse buttons
from /dev/input devices that advertise BTN_LEFT.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds Linux Wayland cursor and mouse-button capture, platform-specific HUD resize anchoring, menu-state IPC synchronization, related tests, and Arch Linux, Omarchy, and Hyprland setup documentation.

Changes

Wayland telemetry and HUD support

Layer / File(s) Summary
Wayland cursor and button capture
electron/ipc/cursor/wayland.ts, electron/ipc/cursor/interaction.ts, electron/ipc/cursor/wayland.test.ts, README.md
Wayland sessions now use Hyprland IPC for cursor positions and evdev streams for mouse-button events. Capture cleanup handles both sources. Tests cover session detection, socket paths, parsing, device capabilities, and button events. README documents Linux runtime prerequisites.
HUD resize anchoring and menu synchronization
electron/hudOverlayBounds.ts, electron/electron-env.d.ts, electron/preload.ts, electron/windows.ts, src/components/launch/hooks/*, src/components/launch/LaunchWindow.tsx, README.md
The HUD reports bottom or center anchoring by platform and session. The launch UI applies the selected positioning. Menu visibility crosses the preload and IPC layers to expand or contract Linux fallback HUD bounds. Hyprland configuration guidance is documented.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 21806

The PR improves Linux Wayland HUD behavior and cursor telemetry, but its recording path may observe mouse-button activity from other sessions on shared or multi-seat systems when those input devices are readable; this bounded permission and session-scoping risk should be explicitly accepted or followed up. The README also needs minor syntax corrections for the documented Hyprland configuration.

Hyprland current window rules syntax match: conditions before effects windowrule documentation

💡 Result:

In modern Hyprland configurations (as of version 0.53.0 and later), the previous windowrule and windowrulev2 systems have been consolidated into a unified windowrule syntax [1][2]. The syntax now strictly separates matching conditions from the effects (properties) to be applied [1][3]. Syntax Structure You can define window rules using either a named block format or an anonymous single-line format [1][3]. 1. Named Rule Syntax: windowrule { name = rule-name match:class = regex effect_property = value } 2. Anonymous Rule Syntax: windowrule = match:class regex, effect_property value Key Syntax Rules Conditions (Matches): All conditions must be prefixed with match: (e.g., match:class, match:title, match:workspace) [1][3]. You must declare at least one match condition for the rule to function [1][3]. Effects (Properties): These are the properties you want to apply to the matching windows (e.g., border_size, float, center) [1][3]. Separation: In the anonymous syntax, you chain conditions and effects using commas [1][2]. Because of the explicit match: prefix, Hyprland can distinguish between matching criteria and the desired effects [1][3]. Migration Note If you are migrating from older configurations, note that windowrulev2 is deprecated [2]. You should convert your rules to the new format [2]. For example, a previous rule like windowrulev2 = float,class:(kitty) should be updated to windowrule = match:class kitty, float on (or simply adjusting to the new match: syntax) [2][4]. There are community-maintained converters available to assist with this transition if you have a large configuration file [2]. For detailed information on available match fields (such as match:initial_class, match:tag, or match:fullscreen) and their corresponding effects, refer to the official Hyprland Wiki's Configuring/Window-Rules section [1][3].

Update the plain Hyprland rule syntax.

The hyprland.conf block uses the pre-0.53.0 syntax. For Hyprland 0.53.0 and later, use match: conditions before the effects, or state the required older version.
