Both keyboard and mouse are extremely laggy on this kernel version, even on a fresh install, once the kernel gets updated it turns the computer almost unusable. Keystrokes take several milliseconds to appear on screen I would say around 500ms (measured in a non very scientifically way).
kernel-5.11.12-300.fc34.x86_64 ← downgrading to this one works
kernel-5.13.10-200.fc34.x86_64 ← faulty
I’m on a Thinkpad Carbon X1, i7, 32gb, all the bells and whistles but with lag in every app
