Thanks for pointing me to "git bisect", what a great feature! I was able to
find the relevant patch:

euler:~/libcairo/cairo> git bisect bad
e4a79db0108be6a2b06dfce51a44bcbdead66ebd is the first bad commit
commit e4a79db0108be6a2b06dfce51a44bcbdead66ebd

    xlib compositor: Support subpixel positioning

    As for the image compository, support a 4x4
    subpixel grid.

It's here:
https://gitlab.freedesktop.org/cairo/cairo/-/commit/e4a79db0108be6a2b06dfce51a44bcbdead66ebd

Does this shed some light why LO 24.2 and 24.8. behave differently? Or how this
patch can cause same letters to be rendered in different ways?

I'm adding Matthias to the CC list, maybe he can provide useful information.
