[2021] CPU usage issues after DT\patch

Logged in after downtime, a bunch of accounts all docked in station, minimised clients.
CPU usage is 10-15% per client instead of around 1.5% per client
Work-around - initiate a session change on each client (change ship for instance) and minimise. CPU drops back down to 1.5% per client.
FYI
/edit - fix doesn't persist. Back to 10-15% CPU after 10 mins
/edit2 - doesn't need a session change, do anything in the client and minimise reduces cpu but only for 10 mins
/edit3 - I'm using more cpu minimised than fullscreen lol
