For some reason when opening the toolbox on Mac it does not allow you to use certain things like the view expander, selection of the hovered item(s) do not work and does not fix its self unless you re-toggle toolbox.
No this has nothing to do with the opened programs or specs. It just happens. It is the same whether I have everything open or just studio.
Just wanted to give a bit more info – this also happens on Windows too, only sometimes, not as often, but especially the lagging part. Oh, and not only that, but the Viewport Frame lags when the Toolbox is open as well sometimes.
