App startup is very slow (>15s) and window control buttons are missing on GNOME Wayland

[HossamMajrashi]

🐞 Issues Overview

I'm experiencing two major problems when using the app on Linux:

1. Very slow startup time — the app takes more than 15 seconds to open.
2. Missing window control buttons — the minimize, maximize, and close buttons do not appear.

These issues have been occurring for a long time and still exist in the latest version.
