I do not see white font previews with Breeze global theme on Arch Linux. Is it still an issue for you?
Some font previews are missing, but I think this is another bug. See bug 442744.

The real problem here is that each theme should have its own icons previews cache: Dark theme should generate white previews and Light theme should generates dark previews, but what happens when you apply any theme is that cache preview is not regenerated so the previous fonts previews remain applied to the new selected theme.
The only solution I found is to remove the content of "~/.cache" folder so the new previews will be forced to be regenerated. See attached video for more info.
