Rose disesase - fluff on leaves

Good morning everyone, I’m new here and not so expert with roses.
I’ve bought this rose from a garden center, repotted and put in a sunny spot ( 6 hours direct light a day) . I saw this morning some kind of fluff on some leaves. Should I worry about it? I searched for insects , but I didn’t find anything.
Thank you in advance

Doesn’t look like a problem. Reminds me of some furry creature like cat or dog walking by and the fluff blew on the rose.
