POTENTIAL FIX FOR INVISIBLE RUNE PAGE WHILE IN CHAMP SELECT BUG
Gyazo
Update: I think I found the solution/cause of the bug.
When I first started league since the update it told me to create a rune page, I didn't do that and went straight into aram. In the lobby the bar that says what rune page you are using was glowing, and when I clicked to edit it did the invisible box. After game from the home screen I created a new runge page, then when I went back into game it fixed it.
Tl;dr create a new runepage from the main menu before joining champ select
