EXWM spinning, keyboard lag, not sure how to diagnose

[doriantaylor]

This is more of a meta-bug to the extent that I could use some help tracking down spinning in Emacs running EXWM. The load on my system is consistently hovering above 1 and emacs is taking up most of it, even when ostensibly idle. A document (or addendum to the README) describing how to profile Emacs running EXWM such that the conditions can be successfully replicated without being to intrusive would be helpful.

Thanks

Maybe try using M-x:profiler-start and then use it until it starts lagging then use M-x:profiler-report. That should give you a list of functions that are taking up the resources and how much they are using.

Yes, profiler should show where the issue lies. Have you tried, did it help? If so, mentioning in the FAQ would definitely help others.
