FWIW, it kind of looks like it’s not something you can probably do much about, aside from completely rewriting your assets using UITK.

As I mentioned, ProBuilder used to exhibit similar behavior (full repaint every frame), until a very recent update. Well, in that update they moved from UGUI to UITK:

Asking around, it seems UGUI just has some issues with certain controls that force everything to repaint every frame, even when no data is changing. I wish I knew more than that, but I guess it’s mostly just an issue with the framework, not your approach/code.
