Which version of Emacs were you testing? There was a bug in Emacs 27 that was mentioned in https://github.com/ch11ng/exwm/issues/633 and has been fixed by then.

This is what M-x version gives me:

GNU Emacs 26.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.12)

So clearly you are not affected by that bug. Is the memory usage always high or does it go down eventually (perhaps after several minutes)? As you may have noticed we disable garbage collection temporarily in certain cases for the sake of performance but the memory should be able to be reclaimed.
