Couple bugs I have noticed since most recent update

Randomly when trying to join a game it will provide an error message 'Error processing a message from a server'

Randomly the client will not display the window to join a game except in the background On this one replication steps for me (Windows 10) -- Launch League of Legends

• Search for a match
• Alt-tab into something else / switch to another window to close a program
• Instead of taking over the screen like it did prior to this update, it will not play audible noise and will come up in the background

Match found audible notification will not play and then audio will lag for ~5 seconds after that

After joining a match then immediately trying to find a match will try to search for approximately 1min then hang, start button will reappear and sometimes a message will appear about unable to join lobby and to please try again (don't remember exact verbage on it, however, have seen ~5 times since update)

• Note sometimes on this one no notification appears and you are just thrown back to main screen
