[CLIENT] Border Map bug (texture bug)

Hi all, I discovered a new bug on the summoner's rift, on the botlane. When you choose a champion like leona, and then you dance with her, some bugs on the border of the botlane happend. How you can see on this sreen. "Theadri1900(me)" has a problem with border of the map.

1. Choose a champion
2. Go on the botlane
3. Go on the border of botlane
4. Dance !
