Mailspring UI errors with Windows 11


Fresh install of Windows 11, fresh install of Mailspring. All the icons along the top bar are showing blank, but are clickable, unable to determine button functionality without hovering over the icon to determine function.

To Reproduce…

Steps to reproduce the behavior:

  1. Install fresh Windows 11
  2. Open Application
  3. See error

Attempted to check if themes were an issue, and regardless of theme choice, icon and images aren’t loading inside the app.



  • OS and Version: Windows 11 Pro [10.0.22000 Build 22000]
    • Installation Method: Installer
  • Mailspring Version: 1.9.2-6e14dad1

Additional Context

First time user, coming over from Postbox for Windows - disheartening to use but I love the potential and would love to use this application as my default app.

Hi @Eajimoba

sorry for the late reply. Did you try re-downloading and re-installing Mailspring? Does this help? I just tried the installer on Windows 11 and was not able to reproduce the issue.
