Can't start the app in cachyos.

**Describe the bug**
Running the AppImage opens the windows but goes no where after seeing the logo, and losing focus turns the windows transparent. Nothing else happens.

**Version and platform**
Find your version at the bottom of the Settings sidebar. Write "unknown" if you can't determine it.
- Buzz version: 0.5.5
- OS: CachyOS (KDE Plasma)

**Logs / additional context**

Start by reproducing the Buzz 0.5.5 AppImage on CachyOS with KDE Plasma and capture runtime logs, since the report provides no logs. Done means the app reaches its usable interface after the logo and its windows remain opaque and responsive when focus changes.
