Description

Maybe this is caused by OMTC. I'll provide more details as I discover them.

Turning off OMTC makes the problem go away. I see this on up to date drivers on Intel Ivybridge on Win7.

Presumably this is a problem with the initial (supposedly synchronous) composition that occurs. Any chance you could check this Jeff? I don't seem to be seeing it on AMD, NVidia or Intel here.

If you use an unoptimized debug build does it happen? i.e. is it just happening fast enough that you don't see it?

Is there code that should prevent the window from being drawn before we have content for it?
