A tissue can break into many small pieces as the load moves, distributing paper fibres well beyond the original pocket. The appearance can resemble lint without meaning that the washer is damaging clothes.
Understanding this situation
Before selecting another cycle, identify the material as far as practical and remove loose pieces by an appropriate garment-safe method. Check the other pockets and the accessible door area. Do not reach into hidden spaces or disassemble the machine simply because fragments remain on the laundry.
A useful next step
Follow the manual for any owner-accessible cleaning after the machine has safely finished. If another permitted rinse is considered, make sure there is no unrelated fault, leak or warning first. For a repair enquiry, explain the known tissue incident so residual paper is not mistaken for an unidentified internal material or a continuing mechanical failure.
