Defense-in-depth against GPU init failures on Snap/Flatpak Linux where the main process stays alive but the GPU process crashes at init and the window never renders. Field data in #7270 (two post-v18.2.4 reports) shows this happens on Ubuntu 24.04+/25.10 regardless of GPU vendor — the driver is core22 Mesa/libgbm drifted from the host Mesa. See §12–§17 in docs/research/snap-wayland-gpu-fix-research.md. Mechanism (electron/gpu-startup-guard.ts): - Content-based crash marker in userData with {ts, electronVersion}. Written before app.whenReady() on confined Linux; cleared via IPC.APP_READY after Angular boot — not ready-to-show, which fires on blank/broken renderers too. - Previous-crash detection: marker present AND recent (<5 min) AND matching Electron version. Staleness bound + version gating drop systemd-SIGKILL-mid-boot and post-upgrade-residue false-negatives. - Env overrides SP_DISABLE_GPU=1 / SP_ENABLE_GPU=1 work on all platforms; auto-detection is Linux+Snap/Flatpak-only. - Non-ENOENT fs errors logged at warn — a swallowed write-fail previously meant the guard could re-enter the loop with no diagnostic trail; a swallowed unlink-fail meant a successful boot could get permanently stuck in crash-recovery. Fallback flag bundle (start-app.ts): --disable-gpu --disable-software-rasterizer --ozone-platform=x11 The pair matches Chromium's GPU integration tests' "no GPU process" invariant; DisplayCompositor handles 2D in the browser process without spawning a GPU child. app.disableHardwareAcceleration() alone does NOT — verified against electron/electron#17180/#20702. The extra --ozone-platform=x11 closes the Chromium 140+ browser-side Wayland/libgbm-dlopen gap on Flatpak (redundant with the existing Snap X11 widening branch; last flag wins). Novelty: R3 survey of VS Code, Slack, Insomnia, LosslessCut, Obsidian flatpak, Firefox snap, and Canonical's gpu-2404-wrapper found no peer Electron-snap implementing an equivalent reactive crash-detection + auto-fallback. Prevailing patterns are manual --ozone-platform=x11, proactive env-sniff, or do-nothing. Review: §14–§15 multi-agent verification on the original PR #7273; re-reviewed via 7-agent multi-review (6 Claude focus-agents + Codex CLI) + 5 research agents here (§17). Live-tested with SP_DISABLE_GPU=1 on a KDE/X11 dev host — window rendered normally via DisplayCompositor. Refs: #7270 |

❓ How to use it
If you need some help, this article on dev.to is the best place to start.
If you prefer, there is also a (long) YouTube video available.
There is another article on how I implement the 'eat the frog' prioritizing scheme in the app.
If you have further questions, please refer to the discussions page.
For a structured walkthrough (web app, install, next steps), see First steps (wiki).
Keyboard shortcuts and short-syntax for new tasks are maintained in the wiki: Keyboard shortcuts, Short syntax.
🌐 Web Version
Check out the web version even though it is a bit limited: Time tracking only works if the app is open and for idle time tracking to work, the chrome extension must be installed.
If you want the Jira integration and idle time tracking to work, you also have to download and install the Super Productivity Chrome Extension.
