@KL1RL Your backtrace is different than the others. Unfortunately, it's missing debug symbols so it will be difficult to pin point the issue. Can you please compile sway from source? It's possible that it's already been fixed on sway master. If you are able to replicate, please open a sway issue with the backtrace and a debug log.
