In your videos, it looks to me like you are clicking directly on the item you want to select - I can’t see the mouse clicks so its hard to know when you are clicking. My issue is that if you click next to / near an item, it gets selected. As @bifterx says,
I have created a new video below that includes highlighted mouse clicks - the mouse click visibility is a little misleading but I wanted to highlight when im clicking to show that the cursor is not touching the items that end up getting selected. When I zoom right in the selection gets more accurate but when zoomed out the mouse is not accurate at all. At the end of the vid, I zoom out and try to click between two of the text boxes (so the cursor is not touching either) but one of them gets selected! If it were possible to show the cursor as a cross hair (as in SU) then one should be selecting where the hairs cross, but in LO its as if there seems to be a much wider area around the cursor when selecting - it’s just not accurate unless you are zoomed right in.
I have noticed this behaviour on every system I have used Layout on so I’m not sure that its the graphics card or driver (as every system has had different cards / drivers and all were kept up to date). I’ve put my graphics card and driver details below (for the system Im on now) just in case, but this has been an issue for as long as i can remember. FYI, I have checked to see if there is a more up to date driver for the Nvidia card but apparently its the most up to date version (see screen grabs below).
