Dark Mode graphics issues

[foxxen]

I've tried searching through the forums but I'm not even sure the search terms I need to figure this out. My screen gets all crazy only in dark mode. As soon as I switch back to the regular light mode, the glitching goes away. Anyone else run into this? I'm using a mid-2012 MBP if that makes any difference.

[doublepost=1540489583][/doublepost]Increasing Contrast in Accessability seems to get rid of it (mostly). But I'm still not sure what the issue is in the first place.

I have a mid 2012 13" MBP and have not experienced this, however I did do a clean install. On the other hand, I also have a 2017 rMBP 15" and experience small "dots" maybe a few pixels wide and one or two pixels high bordering windows for mostly Firefox, but some other apps as well. They kind of blink and react to mouse movement, but go away when I move the Firefox window. I need to see if it shows in a screenshot, and if not I'll post a photo.
