Thanks, now I did reproduce... something. I get the "Marker does not point anywhere" error you describe, but also mentions to other broken functionality, not only the "antiblink": Error in post-command-hook (jit-lock--antiblink-post-command): (error "Marker does not point anywhere") primitive-undo: Marker does not point anywhereError during redisplay: (jit-lock-function 772) signaled (error "Marker does not point anywhere") Error during redisplay: (jit-lock-function 1272) signaled (error "Marker does not point anywhere") Error during redisplay: (jit-lock-function 1772) signaled (error "Marker does not point anywhere") Error during redisplay: (jit-lock-function 2272) signaled (error "Marker does not point anywhere") Error during redisplay: (jit-lock-function 2772) signaled (error "Marker does not point anywhere") If I turn on debug-on-error, I also get the stacktrace below on RET, which runs newline. It seems the problem comes from "syntax-ppss", which is also called from "antiblink". I cannot always reproduce this, and often I can reproduce without needing the "undo". I'll keep investigating: I still don't know which marker the message is referring to. It could be antiblink's marker, but it could be anything else.
