That's copying depth data, maybe stencil too. IIRC that used to hit a
fallback on at least some Intel hardware, maybe it still does. The
code in question on the Wine side will eventually go away, but for the
moment you can try setting the
"HKCU/Software/Wine/Direct3D/AlwaysOffscreen" registry key to
"enabled" (you'll probably have to create it) and see if that makes it
any better. For the Gallium based drivers a similar issue was fixed by
d958202.
