The display of wireframes on background images seems to be working weird.

Its my first post here so excuse me if ill have to reformat it or if i did something else wrong.

So i noticed that when i was working with a background image i could barely see the wireframe of the model i was working on and started tweaking the settings. After some messing around i came to the conclusion that there seems to be a problem with displaying wireframes on background images when x-ray is turned on... seems almoust like the background image display in the back has the priority over the wireframe in the front. The interaction beetwen the x-ray setting and the background image setting seems incredibly weird overal as x-ray can show you the blackened faces but not the wireframe itself. In the end i couldnt find any workable configuration. Anyone knows if this is working as intended or is it perhaps a bug?
