Hi i see this bug since patch 7.10 (i think) and it is still not fix*[zombie-brand-clap]* . This bug happen when syndra use her ultimate and just after she use it, when you are in lock screen your screen is shaking a lot until a few seconds ( 10-15 seconds ). And this bug have already been reported but no rioters answered.
