Thanks, I just finally realized that I can map mouse movement to nil.

(after! lsp-ui-doc
  (map! :map lsp-ui-doc-mode-map
        “<mouse-movement>” nil))

I never use that feature so this worked fine for me rather than digging into why
the <mouse-movement> events were being generated.

Thank you,
