Mouse cursor keep buffering as soon as i receive a dm on instagram !!

I updated my windows 11 on my pc recently and since then my pc has been a bit weird , like it uses a bit more rams and cpu than before , leaving that aside i recently noticed the cursor keeps buffering everytime i receive a message on insta , PLEASE TELL ME HOW TO FIX THIS , also i hope this is not some kind of tracking or something , Help will be really appreciated , i tried online couldn't find an answer

Thanks
