I have a set of personal preferences when I start a new scene. One of them is to disable Deep Shadow in the Render> Preview Shadows menu.
Unfortunately this setting does not seem to save, so I must set it each time I start working on a scene. Not a big thing, but perhaps there is an option I don’t yet know that does allow to save this.
Another problem, a bit more annoying is that when I switch the RMB Popup menu off and the RMB on, I can use this navigation - which I prefer - with the mouse but not with my Intuos Pro, neither when I add rightclick to my pen, nor to the tablet’s buttons. This may be a question for Wacom, but I prefer to ask it here to start with.
