Navigraph Charts Desktop App stops tracking/creates straight lines when out of focus

Simulator Version

MSFS 2020

Operating System

Windows 11

Description of the Issue

I am experiencing an issue where Navigraph Charts only tracks my flight path smoothly when the desktop application is actively in focus as the main window. The moment I minimize the app or open another window over it, the map stops updating. When I bring Charts back into focus, it simply draws a perfectly straight line from where I left focus to my current position, missing all the data points in between.

What I have tried so far to fix it:

  • Verified Navigraph Simlink status panel, which explicitly confirms: “Broadcasted flight data to server successfully” with live coordinates updating.
  • Performed a deep reset of Simlink by deleting the %appdata%\Navigraph\Simlink cache folder and re-linking my account.
  • Ensured my Windows system time is completely synchronized via internet atomic time.
  • Signed out and back into the Charts desktop app to refresh account and session tokens.
  • Toggled the “Enable Moving Map” crosshair icon off and on to break local loops.
  • Switched the simulator graphics settings to Borderless Windowed mode to prevent full-screen app suspension.

Despite Simlink successfully sending data to the cloud servers in the background, the desktop viewer application itself completely drops its network sync the second it loses window focus. Any help or insight would be greatly appreciated!

Hello,

Thanks a lot for the detailed report, we’re investigating.

Also, just so we know

What OS/build are you running?

What version of Simlink and Charts app are you running?

Thanks,

Windows 11 Build 26200.9711

Charts 8.45.0 Build 7a9768

Simlink Version 1.1.41.1805

Are you seeing Simlink react in the same way with Charts web?

yes same issue when using the website and switching tabs/minimising

Thanks a lot, I appreciate the extra info.

We’ll look into this

If you click on the ownship icon, deselect ownship trail and reselect it again, does that fix the trail?

yes it does

Thanks a lot for that, we’ll have a dig into the code and investigate.

Hi…,

This issue similar to Own ship trail doesn't follow ship has been investigated and resolved. The fix will be provided in the next Charts release.

Thank you reporting it.

Cheers

Ian
