Blurry tray icon (windows)

Description

The Mailspring system tray icon appears blurry on my Windows 11 machine.

This looks like a regression: in Mailspring 1.11, the tray icon was rendered sharply under the same display settings. In the newer version, the icon appears noticeably blurred compared with the other tray icons.

I have the scale on my display, at 125%, laptop, display resolution 1920x1200.

To Reproduce…

Steps to reproduce the behavior:

  1. Nothing, just the rendered tray icon.

Expected Behavior

The Mailspring tray icon should be rendered sharply and at the correct resolution, as it was in Mailspring 1.11 (v1.11.0-6193b33c).

As I understood, the one of the new feature brakes it, from the release of 1.12.0:

The Windows tray icon styles have been improved, and a new option allows you to opt-out of the red icon style

Screenshots

Attached screenshots show:

Setup

  • OS and Version: Windows 11 Pro 25H2
    • Installation Method: from github (releases) page, via MailspringSetup.exe

Additional Context

The problem is old, I know, but I see app constantly is updating, and this issue still remains.

This should be fixed in the next release (going out later today), we’ve shipped some higher resolution ico artwork for the system tray!
