Hud-service uses lots of processor sometimes

[florin]

In the last few days I could see hud-service process using lots and lots of processor, it makes the system work slowly for seconds. I usually open it by mistake as I use ALT+TAB to switch windows (and it gets in front of my command) and even if I close the hud by clicking X, I see the processor being killed by it and the ventilation system is freaking out.

See attached screenshot with System Monitor.
