Makes it really uncomfortable to play
This feels like a bug with the depth buffer not clearing fully.
If you change line 54 of Content/Shaders/Edge.glsl to this:
o_color = col;
it will get rid of the edges on stuff but will probably also get rid of those artifacts. I'm not sure why they would not be clearing for you.
Whoa it worked! Thank you very much!
You are probably using Intel GPU, don't you? I had this issue and switching to Nvidia helped.
