Drastic slowdown in a file with many layers

I’m working with a model that probably has around ~200 layers (but the file itself is ~120 MB so it’s not too crazy in terms of geo). The layer panel has become very slow and laggy. Selecting layers, scrolling, creating layers etc is very slow.
Has anyone else noticed this? Should I expect it to be tied to my system?

Edit: some of the slowdown appears to go away if I close most of the properties but I do need them to be able to work

Hi John, we have an open issue to improve this.

Thanks, that’s good to know. The age that open issue has on the tracker is not very encouraging though. :slight_smile:
