It requests tiles if I select "Yes", but the tiles are completely unaligned. Example BBOX: 90.090000,-84.961129,180.090000,5.038871 which likely should be 90,-90,180,0. MapProxy does permit small rounding errors but these numbers are way off.

Thanks for your efforts. Can you mail me a link to the ticket, if you are ready?

That's the standard response of MapProxy for tiled requests with non-matching BBOXs.

It looks like GeoWebCache accepts differences of up to 10%.
