The UI/Tablet - that freeze when pressing buttons


I’m curious. What is it about the way the tablet and UI are setup that causes that brief freeze every time you press a button. This is nothing new and has been happening as long as I’ve been in HF, (a few years) but I figured it would be fixed by now. Can someone explain to me what that’s about? It’s probably one of the biggest obstacles to High Fidelity being a smooth experience we can all enjoy. I havn’t seen anything like this with any other virtual worlds I’ve visited in VR.
