Extreme Lag/Frame-drop in Summoner's Rift Champ Select
I'm having a lot of bugs with the client recently, and I'm probably going to make separate posts for each (will edit in links to others at bottom in case they're inter-related).
I have a large drop off in frames in champ select to the point where I get about 1 frame per 5 seconds at some points on summoner's rift (even on low spec mode), around 1 frame per 3 seconds at worst on ARAM, and almost normal on Nexus Blitz. This was not a problem before 8.15 (so 8.14 and prior was fine). When the bug occurs all videos on my browsers visually pause and are bugged until I refresh the page. Steam also freezes visually if it isn't minimized (different from not responding) which has been happening all season but I am now able to link it to this. Needless to say this bug makes it near impossible to set up runes, ban, change spells, etc. It also appears that it may only happen in premades (or at least is more prevalent) as I tried to take a video of it by myself and it only happened in small, short spikes.
