SlateDrawWindowsCommand take a lot of time. What is it?

Hi there,

I’m running some timing checks on my packaged wip VR game using ‘stat dumpFrame -ms=0.1’
and am finding that ‘SlateDrawWindowsCommand’ seems to be taking a whopping 11ms!

As I am aiming to render at around 10-11ms total this is not good.

What kind of things would SlateDrawWindowsCommand be in charge of doing?
So that I can try to remove or limit this part.

EDIT: I just tried to do ‘stat slate’ but there is says slate only takes about 1.3ms.
Not sure why stat dump has it at 11?
