Hello all, i've started to play league with a friend a few days ago, and she sometimes has this weird bug that makes her screen completely unreadable. If she tabs out, the other tabs work just fine, but whenever she tabs back into league, it looks like this and is obviously unplayable. We're already in low priority queue cause she had so many warning from having to reboot her pc a lot. Anyone know if this bug is known, and what could be the cause ? Thanks a lot in advance.
