Bug report and feature suggestions — Cosmic (Pop!_OS)
Bugs (with reproduction steps and impact)
- Cosmic text editor does not open files via double-click
- Behavior: double-clicking certain text files opens a new empty document in the editor instead of the file contents.
- Steps: open file manager → double-click affected .txt file → editor opens blank document.
- Impact: productivity loss / confusion.
- NumPad (NumLock) state does not persist after reboot
- Behavior: NumLock enabled before shutdown is disabled after boot; must enable manually. Does not occur in GNOME.
- Steps: enable NumLock → shut down → boot → check NumLock state.
- Impact: inconvenience for NumPad users.
- Microphone volume reduces automatically when recording audio (Telegram/WhatsApp)
- Behavior: loud input causes system to reduce microphone gain/volume (e.g., 30 → 17/10) and it does not return to the previous level.
- Steps: open Telegram/WhatsApp → record voice message with loud speech → observe volume reduction and no return.
- Impact: inconsistent voice messages; degraded quality.
- Games do not go fullscreen correctly — dock remains visible
- Behavior: some games in fullscreen leave the dock visible at the bottom over the game.
- Steps: start a game in fullscreen → dock remains visible.
- Impact: impaired gaming experience.
- Cosmic App Store freezes/does not open
- Behavior: the store app hangs or fails to start in some cases.
- Steps: open App Store → app freezes or fails to launch.
- Impact: cannot install/update apps.
Feature suggestions (description and desired behavior)
- Shortcut to show desktop / minimize all windows (equivalent to Super+D)
- Current: no button in the bottom-right of the dock and no default shortcut to show the desktop.
- Suggestion: implement a default shortcut (e.g., Super+D) and/or a dock button; allow customizing the shortcut in keyboard settings.
- Night Light / blue light filter
- Suggestion: built-in option to reduce blue light and warm screen colors on schedule, with adjustable intensity.
- Persist NumLock state across reboots
- Suggestion: save/restore NumLock state between sessions/restarts.
- Microphone AGC control or disable option (Automatic Gain Control)
- Suggestion: add an option in Sound Settings to disable AGC, adjust mic sensitivity/limits, and persist per-app settings.
- “Game mode” to auto-hide dock/panels in fullscreen
- Suggestion: detect fullscreen apps and hide the dock; provide per-app force-hide options.
- Better file-association handling in the text editor
- Suggestion: ensure double-click opens the correct file; add checks for encoding/file type and handle corrupted files gracefully.
- App usage tracking + limits / Digital Wellbeing features
- Suggestion: a Digital Wellbeing panel that:
- tracks app usage (daily/weekly);
- lets you set per-app time limits (e.g., 1 hour for Brave);
- notifies before the limit and prompts to save work;
- closes the app when the limit is reached and blocks reopening per policy;
- supports exceptions (password override, snooze).
- Suggestion: a Digital Wellbeing panel that:
