@xingbugengming: Brothers, it's suggested to turn off these two settings in Codex: I was saying that switching projects and conversations always lagged a lot before, and the mouse sometimes couldn't move. It turned out these two settings were the culprits. I didn't expect the semi-transparent sidebar and dynamic effects to consume a lot of GPU resources. After turning them off, the experience is instantly much smoother.......
