Mac Selection Outlines cover object Pls help

So I think it started in 4.15 or 4.16 and im still not totally sure that it is a bug. It used to be that there was just an outline around the object that is selected. But now it is all 100% colored in. I haven’t heard of or seen this happening with anybody else, so I fear it is a bug. I just went with it when I saw it when I installed the update but its really annoying because I have to click on something different if I want to look at what ive selected. I looked in the project settings but there were no options to change anything having to do with an outline or selection. Please tell me how to fix it. Thanks.
