Running Mailspring on a modern Linux installation isn’t really feasable. You can use Xwayland, but the application will be very blurry if you have a hidpi display.
Yes, native Wayland support is available from Electron 12 on only. Please see this PR for details:
Including this will help Mailspring remain one of the only glossy Email clients on the Linux platform, which with Wayland, HiDPI and fractional scaling is visually polished and up to par with commercial operating systems.
While here came the Mailspring flatpak version i use X11 socket (XWayland) to start the app on Wayland (i use Flatseal instead of command line). But really wait for the native Wayland support.
How did u get it working under XWayland?? I have installed the Flatpak version and it doesn´t work for some reason. Have even tried to use flatpak run --socket=wayland com.getmailspring.Mailspring and still no luck, I get this error:
[2 preload-host-spawn-strategy] Running: /app/bin/zypak-helper child - /app/share/mailspring/mailspring --type=zygote
The futex facility returned an unexpected error code.

So yeah if u can direct me maybe. Thanks in advanced. Also using Fedora 35
