Description

Detects Hyprland sessions on Linux and defaults Electron to X11/Ozone to avoid the Hyprland hover crash/disappearing window issue.

Motivation

Fixes #638.
Recordly can disappear/crash when hovering the UI on Hyprland under native Wayland/Ozone. Manually launching with --ozone-platform=x11 fixes the issue. This PR applies that workaround automatically for Hyprland users so the AppImage works out of the box.

Type of Change

  • Bug Fix

Related Issue(s)

Fixes #638

Screenshots / Video

Not applicable. This is a Linux startup/runtime compatibility fix.

Testing Guide

Tested:

  • npm test -- electron/gpuSwitches.test.ts
  • npx biome lint electron/main.ts electron/gpuSwitches.ts electron/gpuSwitches.test.ts
    Manual test:
  • Open Recordly on CachyOS + Hyprland.
  • Hover over the UI.
  • Press Record.
  • Confirm the app no longer disappears.

Checklist

  • I have performed a self-review of my code.
  • I have added any necessary screenshots or videos.
  • I have linked related issue(s) and updated the changelog if applicable.

Summary by CodeRabbit

  • Bug Fixes
    • Improved Linux display compatibility for Hyprland sessions by automatically selecting the appropriate Electron windowing platform.
    • Preserved explicitly configured Ozone platform settings, including X11 and Wayland selections.
    • Improved handling of invalid platform settings to support reliable graphics initialization.
    • Applied the selected platform during app startup for more consistent window rendering across Linux desktop environments.

📝 Walkthrough

Walkthrough

The PR adds Hyprland session detection and Linux Ozone platform overrides. Hyprland defaults to X11 unless OZONE_PLATFORM explicitly specifies a platform. Linux GPU switch setup applies the override when no existing Ozone switch is present.

Changes

Hyprland Ozone handling

Layer / File(s) Summary
Ozone platform detection and validation
electron/gpuSwitches.ts, electron/gpuSwitches.test.ts
Defines the LinuxOzonePlatform type, detects Hyprland sessions, resolves X11 overrides, removes the ELECTRON_OZONE_PLATFORM_HINT fallback, and tests forced, explicit, and non-Hyprland cases.
GPU switch configuration wiring
electron/main.ts
When Linux has no existing ozone-platform switch, derives the environment-based override and appends the matching Electron switch.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 134f2

This change defaults Electron to X11 for Hyprland sessions to prevent startup and hover-related crashes, but a visible update toast can still block Linux tray actions until the toast is dismissed; the PR is mergeable with explicit owner awareness or follow-up for that bounded behavior issue.

262-268: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not let a visible update toast block HUD access.

On Linux, tray Open and Show Controls call these paths. When the update toast is visible, both paths focus it and return before they restore or create the HUD. The user must dismiss the toast before they can access recording controls.

  • electron/main.ts#L262-L268: Let showHudOverlayFromTray continue to the HUD path when the user requests controls.
  • electron/main.ts#L341-L347: Let focusOrCreateMainWindow continue to the main-window or HUD path when the user opens Recordly.
