Turn off showfps.
Spent a little bit of time trying to fix it a while back and didn't find out how, so you'll need to just turn it off. net_graph 1 works though, but it impacts fps more
Customising has been a lot harder than I thought it would be (each org has a different dll & materials), but you can change position with advspec_medic_info_offset_x & _y. (negative numbers with showfps won't work)
