Purple outlines on objects (selection cues) on mouse hover don't go away

[NPriore]

I've only been using AD for a couple of weeks and I find it easy to use, but after I updated to the latest version yesterday I notice this issue with these purple outlines on objects.
Whenever I hover my mouse over an object, a purple outline appears on that object. As I hover my mouse over other objects the same thing happens to those objects. That outline does not go away when I move the mouse cursor away from the objects. It does go away eventually but I don't know why it takes so long to disappear. AD was not behaving this way before the update. 
Is this a bug or a setting that I now need to adjust? I searched the forums and the help file but could not find anything related to this issue.
Please help! Thanks.
See the video I've attached.

I think I found what was causing the problem. In the "snapping" options I unchecked "show snapping candidates" and that appears to resolve the problem. I don't know how or why that option was turned on but it looks like that was the problem.

Hi @NPriore,
Welcome to Affinity Forums
Yes, the purple lines do represent snapping candidates. You can partially disable them as you did or by changing the Candidates dropdown to something other than Candidates List.

I see that now, Thank you. 
AD is very impressive and easy to learn. I'm enjoying working with it. New features are great. 👍
