Thanks for your quick return... and sorry for not having seen this issue, I missed it ;-)
I'll read it carrefuly, test some improvement mentionned, and get back to you quickly if It's not concluant (with sample or private repo).
I already know that I abused of Shadows... we put them everywhere ;-)

Hey Jerome !
Nice UI ;)
Normally if all items have the same size (which seems to be your case), Shadows should be reused thanks to cell reuse.
You can have a look at this issue: #16
If you have still issues, you could share with me your app on a private repo and I could investigate :)

Ok, did more tests and improve our lists, and Shadows don't realy have bad performance... I think it's normal to have some slowing with all these cells renders (it's more our using and abusing of it ;-))

Can close this issue.
Thanks

@Jerome-Liger This could be the performance issue itself of the CollectionView. You can check out this blog post for some improvement tips: https://codetraveler.io/2020/07/12/improving-collectionview-scrolling/
