Cover won't show

**Describe the bug** Pressing F8 used to show cover art of the currently played song. This doesn't work any longer, the screen doesn't show an image. Running "$ueberzugpp layer --silent" and pasting e.g. the json snipped shown in /tmp/ueberzugpp-$USER.log is being displayed in Kitty correctly. **To Reproduce** Steps to reproduce the behavior: 1. install the latest version ($cargo install ncspot --features cover --locked) 2. start ncspot in Kitty 3. play a song 4. press F8 **Expected behavior** Pressing F8 should display an image (cover art) **Screenshots** <img width="1900" height="1288" alt="Image" src="https://github.com/user-attachments/assets/846d58f6-2389-4dc1-bc53-c1512f22a149" /> **System (please complete the following information):** - OS: CachyOS (Linux pulsar2 6.18.9-2-cachyos x86_64 GNU/Linux) - Terminal: Kitty 0.45.0 - Version: ncspot V1.3.3 - Installed from: cargo install ncspot --features cover --locked - DE: KDE6.5.5 plasma / KWin (Wayland) **Backtrace/Debug log** debug doesn't show any errors or warnings.

Subsequent songs won't write into the log anymore (stuck?) if switching to the cover-screen.
