The only other thing I have tried when colours don’t work right is to modify the metacity and gtk theme files. (Save a backup first, then) modify the colours of various white elements to various ones in the rainbow until the mozc popup colour changes. Note that you have to restart every time for it to take effect.
On Lemmy, two’s a crowd (or a flamewar).
