Linux snap package has the wrong mouse cursor

Description

The Linux snap package for mailspring does not use the system mouse cursor. Instead, it uses the fallback, 1980s-style black X cursor.

To Reproduce…

Steps to reproduce the behavior:

  1. Boot a Linux system with support for snaps, such as Ubuntu. (Might be DE-dependent. I’m using Kubuntu 21.04 with KDE Plasma 5.)
  2. Install the mailspring snap package.
  3. Launch mailspring.

Expected Behavior

The mouse cursor matches the rest of the system.

Screenshots

Setup

  • OS and Version: Kubuntu 21.04
    • Installation Method: snap
  • Mailspring Version: 1.9.1

Additional Context

The Chromium snap uses the system cursor somehow, so it’s definitely possible.

Good point - I’d not spotted this but you’re right (Kubuntu 20.10 here). And, like you, all my other snap applications respect the system cursor setting.

You could try depending on the gnome-3-28 extension. The Chromium snap depends on it. Its description says: “It initialises GTK3 and the desktop environment before your application starts so functionality like fonts, themes and a11y works correctly.”

Seems to be doing the same thing here on Ubuntu 21.04. Mine changes to a very small black cursor. I’m running a 4k resolution.
