SysCubesOverlay Troubleshooting
Keep performance readings and practical PC controls beside your game. Start with the running game's profile, then follow the SysCubes status to restore widgets, adjust cursor interaction or choose the supported display mode. Each check below gives you a clear next action.
Use this illustrative checklist beside the app to connect the game, profile and visible layout.
Quick answer
Start a supported game, enable its SysCubes overlay and include at least one enabled widget. In Overwolf Settings > Overlay & Hotkeys, confirm the overlay is allowed for that same title. Then read the SysCubes status: restore Hidden with Show overlay, check display mode for Exclusive fullscreen, or follow the error for Unavailable and Needs attention.
Start where the problem is
Choose the state you can see in SysCubes, follow the manual checks and mark your progress. Test one change before moving to the next.
SysCubes has a per-game profile, and Overwolf has its own overlay setting for that title. Both need to permit the overlay.
Return to the game, read the SysCubes overlay status and follow the matching entry in the status table below.
Mark these manual checks as you try them in SysCubes. Your progress stays on this page and resets when you leave.
Establish the connection
Launch the title and check that Overwolf detects it. Use Overwolf's supported-games list for the exact game and version. A working desktop dashboard does not establish in-game overlay support. If the app reports Unsupported game, use the dashboard or second screen instead.
Open Settings and select the game you are actually playing. Enable its overlay. The running game's saved profile controls the in-game widgets even while Settings is viewing another game, so editing the wrong profile can leave the active game unchanged.
Check that the widget is enabled in the app and selected for this game's overlay. Overlay on with no included widgets produces No widgets selected. Start with one Performance widget in a visible position to keep the first check simple, then add the rest of your layout.
In Overwolf Settings > Overlay & Hotkeys, locate the same game and allow its overlay. Return to SysCubes and read the status before changing another setting. If the profile is waiting for a different game, Ready for next launch is expected rather than a failed connection.
Use a recent app package and Overwolf client. Re-test in the same game, scene and display mode after each change so you can see what restored the layout. Once one widget appears, add the readings and controls you want beside it.
A practical status reference
The status explains which part of the setup needs attention. It is more useful than treating every missing overlay as a permission error.
| Status | What it means | Next action |
|---|---|---|
| Waiting for a game | No game profile is available for the current selection. | Launch the game and check detection, then select the intended profile. |
| Unsupported game | Overwolf does not provide an overlay for this running game. | Check the exact title/version against the supported-games list. Use the dashboard when unsupported. |
| Off / No widgets selected | The profile overlay is off, or has no included enabled widgets. | Enable the game profile and select an enabled widget. |
| Ready for next launch | The chosen profile is not the currently running game. | Launch that title, or select the profile for the game already running. |
| Hidden | The overlay is hidden for this session. | Use Show overlay or the assigned show/hide shortcut. |
| Starting / Connecting | The overlay service or game connection is being established. | Allow startup to finish. If it persists, record versions and check a fresh relaunch. |
| Unavailable / Not connected | The overlay service failed to start or the native connection is absent. | Restart the app for Unavailable. A browser preview cannot provide a Windows game overlay. |
| Needs attention | The overlay supplied a specific failure message. | Read the error and use Retry overlay when offered. Collect evidence if retry fails. |
| Exclusive fullscreen | The current game/display configuration limits overlay behavior. | Try supported borderless/windowed settings and follow the title's current Overwolf instructions. |
| Active in game / Interacting / Game in background | An overlay is present; its focus or interaction state differs. | Return focus to the game, check locks and use Escape to leave cursor interaction. |
Visible widgets, usable controls
A locked widget body lets clicks reach the game. Its unlock control remains available. Unlock the widget before dragging, resizing or using its controls, then lock it again when you want clicks to pass through. Locks and positions are saved per game.
Games that hide the pointer can use the profile's Show widget cursor shortcut. Return focus to the supported running game first. Escape leaves cursor interaction and returns input to the game. If the game already provides a cursor, try direct widget controls.
If Show overlay works but the assigned shortcut does not, check that running game's binding for conflicts with the game or another overlay. Test a distinct available combination. Use the profile's shown binding rather than assuming every title shares one global default.
After changing resolution, scaling or monitors, open the layout preview in Settings and check the affected game's saved positions. Confirm the intended display and resize or place the widget inside the game area before retrying. A widget outside the visible area can look like a connection failure.
Follow the game's supported path
Overwolf and SysCubes have separate responsibilities: Overwolf provides the supported game overlay connection, while SysCubes selects the profile, widgets, layout and interaction controls. A game can also supply an overlay without supplying the FPS events a performance widget needs.
Check current platform status if game-event features suddenly stop working. A temporary game-event outage can affect FPS or other event-dependent data while desktop controls continue to work. Avoid interpreting an unavailable FPS number as proof that the entire overlay failed.
Follow the supported configuration for your game's version and graphics mode. If its in-game overlay path is unavailable, the second-screen dashboard gives your supported PC controls a useful place beside the game.
Startup failures and unresolved issues
If the dashboard will not stay open, resolve that startup issue before testing the overlay. If it opens normally, keep the game-specific status and reproduction steps together.
| Record | Include |
|---|---|
| Environment | SysCubes version, Overwolf version, Windows version and the package/test channel used. |
| Game and display | Exact game/version, display mode, graphics API when known, resolution, scaling and monitor layout. |
| Profile and visible state | Running-game profile, included widgets, locks, overlay status and complete error text. |
| Reproduction | Whether it fails with app-first and game-first launch, after Alt-Tab, or after a resolution change. |
| Comparison | Whether the dashboard opens without a game, whether Show overlay works, and whether the issue affects one title or several. |
| Current diagnostics | Fresh app and Overwolf logs from the affected session, reviewed for personal details before sharing. |
Use the complete app package provided through your release or test channel. Keep its files together, reopen the dashboard and test the game connection again.
If the overlay is visible but CPU temperatures are missing, use temperature sensor setup. If readings are present but your game slows down, use FPS drop troubleshooting to investigate the workload separately. Check current download availability before relying on an installation route.
Your questions, answered
Check the running game's SysCubes profile: its overlay must be enabled and at least one enabled widget must be included. Also check that Overwolf supports the game and permits its overlay in Overlay & Hotkeys. Then read the app's status: Hidden, Unsupported game, Exclusive fullscreen and Unavailable require different next steps.
Overlay support and configuration are game-specific. Each game can have different Overwolf compatibility, display-mode requirements, selected widgets, lock states and shortcuts. The running game's profile controls its overlay, even if Settings is showing another profile. Compare the affected game's own settings and status rather than copying assumptions from a working title.
Locked widget bodies pass clicks through to the game. Use the widget's unlock control before moving or adjusting it. If the game hides the cursor, use the running profile's Show widget cursor shortcut. Press Escape to return input to the game. Placement in Settings remains available if in-game interaction is unsuitable.
No universal display-mode rule applies to every game. If SysCubes reports an exclusive-fullscreen limitation, try borderless windowed mode where the game offers it and follow Overwolf's current instructions for that title. Some games impose more specific requirements. A display change does not guarantee overlay support or override game restrictions.
Start with the supported game, correct profile, enabled widgets, Overwolf toggle and visible status. Elevating the whole app is not a universal fix. Follow current Overwolf guidance for a diagnosed permissions issue. Optional CPU sensor setup can require administrator approval separately; that approval does not establish overlay compatibility or fix a missing game connection.
