Product gallery animation problem

Hello,

Since the last update i see an animation when the product pages are loading in the website.
Analysing the problem with lighthouse i can see an animation starting this seems to be penalising me with core vitals.

i use the standard product galery and therefore i don’t know what could cause it.
