[Severe Scroll Menu Lag?]

Hi just bumping this as I am experiencing similar issues, nobody else is experiencing the same issues as I am on the server.
Just to be clear it's basically all mouse scroll menu's that are lagging, later the option sometimes appears.. Sometimes it takes a few seconds, sometimes it just doesn't show a menu at all even stood still in front of trader for 5 minutes.
Most of the time it works fine but it keeps happening at the worst of times!

When I've checked in the past its been just surface noise spam

Other symptoms are white text lagging in bottom right and lower fps than usual
