High memory usage

Hello! Thank you for the program. I've started creating a loot table for an easy base, and I've run into an issue where the program is already consuming ~5GB of memory (and I haven't finished adding loot yet). The file size is 90KB.

UPD. After saving the file, memory consumption decreased to 1400MB.
However, the program window still lags when I try to add a new item via right-click.

UPD2. Again usage increased to ~6GB.

I could be mistaken, but it seems to me that the problem(window lag) lies in the circle animation.

I will investigate later what is causing this, maybe send me the json you were working on in case it was related.
