Mailspring 1.10 still uses Xwayland when Wayland interface is available

Description

I was very excited to see that the new 1.10 release of Mailspring upgraded to Electron 14 and enabled Wayland support. However, upon upgrading it is still using XWayland as an interface, which makes things quite blurry (I am using fractional scaling on Gnome-shell 41). Is there a way to force Mailspring to use the native Wayland interface?

To Reproduce…

Steps to reproduce the behavior:

  1. Install Mailspring 1.10 via Snap
  2. Run xeyes
  3. Run Mailspring
  4. Observe that Mailspring is using XWayland (via Xeyes moving)

Expected Behavior

Mailspring to use native Wayland interface and only fall back to XWayland if needed.

Actually you can start mailspring on Ozone/Wayland with:

mailspring --enable-features=UseOzonePlatform --ozone-platform=wayland

The initial setup of the account works flawlessly and let me configure my Gmail account.

Still at the end of the day if I try to click on the systray icon I have the app freeze on the cli and eventually crash:

Just adding to this that the latest Mailspring under Wayland is also not running for me. Running under the default xwayland works fine, however attempting to run with the Wayland flags just bombs. Happy to help debug this further.
