XWayland crashing due to Firefox getting connection reset by peer

I'm getting

Gdk-Message: 16:46:37.519: Error reading events from display: Connection reset by peer
(EE) failed to write to XWayland fd: Broken pipe
/home/USER/.nix-profile/bin/nixVulkanNvidia: line 6: 3910437 Terminated "$@"
Gdk-Message: 16:46:37.603: firefox: Fatal IO error 11 (Resource temporarily unavailable) on X server :1.

It has happened twice. Seems to be something with Firefox. I dont know if this is due to Simula but Simula is what is crashing.

Do you have a way to reproduce it? Any sites you visited, etc. Does it crash on a clean profile?

this may be a duplicate of #193 though I seem to get a different stdout response
