It might be that the implicit -multimonitors with -multiwindow is doing is
throwing things off somehow (rounding?), so you might want to test with
-rootless -multimonitors and -multiwindow -nomultimonitors and see if that
changes anything?

No and yes. That is the legacy (core) font rendering.
Modern applications will use client-side font rendering and just send an image
to the server using fontconfig/Xft/XRENDER.
This would tend to suggest there is something in the font rendering on the
Centos host which doesn't respond well to something about multiwindow mode,
but I don't know what...
