Original report
Omarchy 4.0.0rc5-1 ships and migrates Ghostty configs with:
Fix general slowness on hyprland (https://github.com/ghostty-org/ghostty/discussions/3224)
async-backend = epoll
On this x86_64 system, Ghostty 1.3.1-2 has produced ten SIGSEGV coredumps between Aug 7 and Aug 14, 2026.
The current crash:
- Thread: io
- Signal: SIGSEGV / SEGV_MAPERR
- Fault: ghostty + 0x151c90d
- Instruction: mov 0x108(%r14), %rcx with r14 = 0
A matching Ghostty/libxev source build maps the identical instruction sequence to:
libxev/src/queue.zig:48
queue.Intrusive(WriteRequest).pop
The call originates from the epoll-specific queueWrite callback. The core shows the write queue head and tail are both null even though the callback assumes a queued request exists.
Notably, libxev's own queued-write test skips the xev.dynamic + x86_64 case with:
"this test fails on x86_64 with a strange error"
Expected behavior is for Ghostty to open terminals without crashing. Please consider removing or disabling the epoll workaround until the upstream libxev/Ghostty queue issue is fixed.
System:
- Omarchy 4.0.0rc5-1
- Ghostty 1.3.1-2
- Linux 7.1.8.arch1-3
- Hyprland 0.56.2-1
- Wayland 1.26.0-1
The documented omarchy debug --no-sudo --print command is not available in this Omarchy release.
