[CLIENT] Client in champ select is extremely laggy

I've never had this issue until the past month or two with this client, and I participated in it's alpha. When I get into draft select-type champ selects, the client is extremely laggy and seems like it is skipping several frames at a time. It almost causes me to unintentionally dodge when banning a champ (because the ban won't go through), and has made me take sub-par runepages on several occasions.

I guess I'll try low-spec mode, but my computer should be able to handle it normally. Any other solutions?
