Loading screen map image and tips background missing

[KiiLsTriiKeRrR]

On the 1024x768 @60Hz Resolution, at some maps the map overview image (top right) and the background of the 'tips' section (left) are missing. I don't know if this happens at other resolutions too, but it does happen at the resolution above.

It's beta, not every map have they loading background and map overview yet.
