Disable demo recording hud / removing derma panels


I’m trying to autorecord on my server but as soon as I start to record a big OREC hud symbol, which garry apparently added
with garrysmod 13, blocks like half of my screen, is there any console command to disable it?

Another big issue that I have is that derma panels leak memory.
I remove the panel with various subpanels, including model panels, but it does free the memory used.
Is this a garrysmod bug or do I have to do somthing special to remove the panel from the memroy?

Thanks in advance
