Friend list may be the cause of Black screen

Hi riot and other players who have the issue of the black screen issue. This is me speaking my mind about the black screen. I think the friends list is the issue and i found a certain way to fix it. For any reason, the friends list is causing league to bug/freeze, but it does not crash. To fix the problem of the black screen, if you minimize the friends list. It reduces the lag that cause the black screen. If you read my post and this helps, please reply.
