Hi i was not able to find my solution in the search, but i believe there is a solution somewhere already.

My problem is that when i point my mouse on an item (for example artifact with long description) it goes out of the window to the left.

Any help is appreciated.

That's been around for a while, there's nothing to do about it. It's been bugging me as well. Maybe change browser? I get this on both firefox and chrome, though..

Well thats a disappointment.

Play GL on fullscreen or simply move your mouse around and approach the artifact with your mouse from the left side.
