White backgrounds appearing unexpectedly with Horizon theme

I’m not a developer, so I’m unsure whether this is a bug in Horizon, a recent Discourse change, or something specific to my configuration.

It’s helpful to try in safe mode, to see if it persists, and also try on Foundation please. It helps to narrow things down.

Also have a look if you have any upcoming changes only enabled for staff maybe, could be a culprit too.
