Description Amy Kay 2025-12-31 00:20:26 UTC 
SUMMARY
I use Ghostwriter nearly everyday, only started encountering this bug on my second PC (with a new fresh linux install).

Terminal output:
akay@fedora:~$ ghostwriter
[     0.296 24709 ghostwriter ] INFO      Backup files will be stored in "/home/akay/.local/share/ghostwriter/backups/"

[     0.564 24709 ghostwriter ] WARNING   GBM is not supported with the current configuration. Fallback to Vulkan rendering in Chromium.
Segmentation fault         (core dumped) ghostwriter

STEPS TO REPRODUCE
1. Install Ghostwriter through the third-party Fedora repo or from flathub
2. Launch Ghostwriter through the GUI or TUI
3. Wait a moment, then it crashes
