Any way of not displaying white mesh border lines in 3D viewport when texture painting? I'm painting a mesh with two materials, but I don't want to paint over the other materials, so I have the "face selection masking for painting" on. 
The problem is that it shows these white mesh lines.
Is there any way to turn that off, so it's easier to see what I'm painting?

I don't remember this being a problem in 2.79
