with classic theme (windows 2000 like) multiple renderer get the content mixed:

but with standard theme (aero on) looks like this:

Here it works just fine…
this looks quite odd. no idea what could cause that. running myself one pc on aero and another without. never seen anything like that. i’d try a driver update…
I have installed the latest drivers. Will try to look in detail this problem.
