my editing mode (x-ray activated) is not allowing me to see the reference behind. the edges are thick black and faces are white. any suggestion? The mesh in edit mode with x-ray activated is colored white with black thick lines, which means, I cannot see the reference image behind. I was working normally until that happens, I didn't know how to fix it, I searched a lot for something that matches my case, but there aren't any.
If you see your mesh white while x-rays enabled means your shading mode may be in solid. Try to switch in wireframe shading with x-ray enabled.
Edit: If some faces look different in X-rays, you can also try to Recalculate normals (Ctrl+Shift+N).
You can quickly change shading with Z key, while Alt+Z will toggle x-ray
