New portal expanding, antialiasing enabled

Kubuntu 11.04 x86_64 running Wine 1.3.18 from wine ppa (plus winepulse
patches). Portal 2 was downloaded via Steam and then patched with the fixed
SKIDROW crack. Videocard is an Nvidia GeForce 580 running the proprietary
270.41.06 driver from natty restricted.

When creating a new portal, a completely black form of a portal is allocated on
the target surface. In the middle of this, the actual portal opening animation
starts, which will expand and and eventually fill the allocated black space.
This only happens with antialiasing enabled. With it disabled, there is a form
of warping effect which doesn't seem to work alongside antialiasing.

In the terminal, one line is constantly spammed;
  err:d3d_surface:surface_blt_fbo >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glBlitFramebuffer() @ surface.c / 3460
(Not attaching a log with thousands of those identical lines.)

See attached screenshots.
