I haven't seen anything like that lately! Doom Emacs, Emacs 28.2 and Manjaro Linux here.

Seems like it only happens on a specific file. Could it be a corruption on the file or with it’s location on the ssd? Although it doesn’t happen every time I save.

I'm not sure! I'd probably ask on the Doom Emacs discord -- there's some very knowledgeable Emacs people hanging around there.

yeah, I guess I should do that. Thanks

@U7AMPCPU2 are you on a Mac? Are you using native-comp? I find native-comp insanely unstable on Mac. After many months of struggle, I finally started building Emacs without the native-comp support and it's much more stable. Even though it supposedly should be slower, I have not noticed the alleged lag. Ironically, with native-comp my workflow slows down significantly, because native-comp constantly has to compile something

IME native-comp is super stable on Intel Macs. I occasionally get crashes on ARM Macs but that is when I have dozens of packages loaded and its hard to reproduce the crashes. They happen once in a few days, but not often enough that it annoys me. Ironically, ARM Macbooks are the only computers I've had Emacs ever crash on.

Yeah I am on mac but not using native-comp.

set the cursor on a thing and run describe-char. See what text properties attached, what faces get used

thanks! likely related to font-lock in clojure mode, will have a look now.

font-lock-type-face needed to be added to rainbow-identifiers-faces-to-override, seems I picked that up from spacemacs: https://github.com/syl20bnr/spacemacs/blob/3512e43c9e6efef78b5104785c99518eff60d668/layers/%2Bthemes/colors/packages.el#L95 cheers for the help, works as expected now
