The F26 background does not change with the time of day, so that
needle should serve as-is, it's just no use for Rawhide. For
Rawhide, let's try a needle with an OCR match on 'Activities',
plus a tiny match area for a pure white block (expected to be
matched in the user menu area), since os-autoinst requires all
needles to include a match area for some reason.
