The same search, immediately repeated from the same directory. More accurately, the first time I invoke xref-find-references in the top-level directory of the Emacs repository, I get 980 matches; thereafter, all the subsequent searches from the same Emacs session yield 1128 matches. This is with the ID database present in the top-level directory.
In the same scenario, I consistently get 1076 matches (on a GNU/Linux system): https://asciinema.org/a/69fdwo7os38fxu01e4fcwftwv
All the searches are done from *scratch* in "emacs -Q".
The screencast above starts from Dired, but it's the same if I start from *scratch*.
Let me know if I can provide more info.
Could you compare the lists of matches you get? E.g. C-x C-s on the xref buffer in both cases, and then diff the results.
