What did i do?
I wanted to do a couple of testings on multiple champs and for that i used practice tool.
I don't really know the number of times i used it but maybe 20ish?
1. Get into practice tool.
2. Attack the dummy for a few minutes.
3. Leave the game with "close client" option disabled.
The more times i did this the slower the client became, until i was unable to pick a champion in champion select. That's when i decided to record an iteration and hope you guys fix it xD
Notes: Even without the bug on, you can notice that when i refresh the client (i.e close and open) the client is still slow (because of my pc, recorder, etc..), BUT there's still a notable difference between joining the champion selection screen (i could finally do that), and time of leaving a game and returning to home.
What i mean is that even without the recorder i wasn't able to join champion selection screen, and it took an infinite amount of time to get home.
I reported it here because:
1. It happened on pbe
2. I'm pretty sure there has been an update (?) on client performance on pbe, so this might help if it gets fixed.
