Some items double in size

The following is an example of what I mean - what is weird is that I checked internal sizing and it all lists the same size for each element - which differs from the transform being applied. All indexes are different, this doesnt seem to happen every single time.

I dont know if I can get a reproducible example just yet

I have been having this same issue where the translate is over calculated. I am able to reproduce by going to a different tab while the list is being rendered/updated and when I return to the tab with the list it has extra spacing between some of the rows. Please note that in my application we are adding and updating this list almost constantly so the bug happens while the list is updating and you are on another tab.
