League Displays wallpaper keeps glitching out

I doubt it's only from league, but a lot of the times after I play a match the wallpaper from league displays just changes to some kind of weird pattern. If this has happened to you can you help in any way? (this doesn't happen for screensaver) It goes from this: https://gyazo.com/dd823b4ba8c227e830bf655ccacd5d4b
